AbstractFor our Senior Design Project we chose to design and build a Human Powered Vehicle (HPV) for the ASME HPV competition. The competition will be held May 1-3 at Portland State University in Portland, Oregon. Our goal is to create a HPV that can successfully compete in three separate areas at the competition; these areas are speed, endurance, and design. This portion of our senior design project is the project proposal. Over the next few pages we delve into the HPV world and show our progress from our initial design concept to our current proposal. We begin at the basics, introducing the concept of a HPV and the requirements that we would have to meet. Moving through the proposal we provide insight on how we developed our four basic concepts and then how those concepts were logically and systematically eliminated until our final concept was reached.

1. Context

1.1. Background of NeedFor our project we will be competing in the ASME Human Powered Vehicle (HPV) Challenge. Our HPV will be in the Single-Rider category and must be solely powered by one person. We will be competing and scored over four categories; design, speed, endurance, and a final project report. Our customers consist of the ASME competition, its judges, and ourselves; since many of the characteristics of the vehicle must be tailored to our ability to drive the vehicle. Each group member must participate in the endurance portion of the competition, so ergonomics for each rider in the vehicle is inherently necessary.

Our Single-Rider HPV must comply with all of the following rules which can also be found in the ASME Human Powered Vehicle rulebook which can be found on the ASME HPV website.

FairingAll vehicles in all classes of competition are required to have a full or partial aerodynamic fairing. This fairing must cover 1/3 of the frontal area of the vehicle and be built such that it clearly shows the provided number assigned to the vehicle and ASME logo. The number and logo must be displayed on every fairing in front of the rider and must be visible from both sides of the vehicle.  

SafetyAll vehicles and teams in all classes must abide by all the safety requirements.

1. Make a complete stop in a distance of 20 feet or less from a speed of 15 miles per hour 2. Travel in a straight line for 100 feet 3. Negotiate a turn within a 25-foot radius 4. Provide rollover protection for riders and stokers, equivalent to chrome-molybdenum steel

tubing with an outer diameter of 1.5 inches and a wall thickness of no less than 0.049 inches 5. Wear helmets that meet given standards 6. Wear seat belts or shoulder harnesses, in accordance to the rulebook 7. Show that all surfaces of the vehicle, both exterior and interior region of the rider(s), are

free from sharp edges and protrusions

Energy StorageThe use of energy storage devices by non-utility vehicles is prohibited. Normal operating components involved in the drive train are specifically permitted in as much as their design is not primarily influenced by energy storage considerations.

Design Judges will consider both the formal written report and the oral presentation when

Page 8: Human Powered Vehicle CompetitionChris Jacobshome.sandiego.edu/~dmalicky/MENG491/Proposals/HPV…  · Web viewOver the next few pages we delve into the HPV world and show our progress

reviewing vehicle designs. There will be an emphasis on originality and the soundness of the design. The focus will be on the new work that has been completed in the last year.

Sprint Approximately four hours of competition will be run on a single track such that everyone will be capable of obtaining a sprint time. The timed portion of the course is a 100 meter straight-a-way. There will be a preceding distance of 300 to 400 meters for vehicles to gain speed before entering the timed portion, as well as a minimum of 200 meters at the end for the vehicles to slow down.     

EnduranceSingle Rider and Multi-rider vehicles will compete in grand prix style road races of approximately 65 kilometers (40 miles). Vehicles must start the event with female rider(s) who must complete at least 5 kilometers. No individual can compete in the vehicle for more than 20 kilometers, and all laps by any individual must be consecutive. When the lead vehicle crosses the finish line, each team will be allowed to finish the lap it is on to end the competition.

This need comes from the fact that we are in a competition and can not compete without completing the analysis and creation of our Human Powered Vehicle. The significance of the problem comes in the fact that it will be the first time USD competes in the competition and we will be understaffed with fewer resources; but we still want to be very competitive.

1.2. Customer Need Statement

The American Society of Mechanical Engineers is putting on a national competition for colleges to compete against each other using their creativity and course work to build human powered vehicles. As a customer, ASME’s need is simple; they need competitors to enter their competition with HPV’s that not only meet the stipulations that they specify in the ASME HPV rulebook, but they also need their competitors to bring creativity and innovation to push the limits of competition and stimulate the minds of college students across the country. As a customer, we need to adhere to the guidelines provided by ASME and create an HPV that is capable of competing alongside many of the top ranked engineering programs in the country

1.3. Literature Review

1.3.1. Prior WorkThe unicycle was one of the first human powered vehicles, introduced into society more than 200 years ago. As changes were made to its design the bicycle was born, and became the desired design. After 200 years of modifications the bicycle has evolved from a rickety machine to increase the speed of transportation to a modern commodity that has a variety

Page 9: Human Powered Vehicle CompetitionChris Jacobshome.sandiego.edu/~dmalicky/MENG491/Proposals/HPV…  · Web viewOver the next few pages we delve into the HPV world and show our progress

of uses. The prior work done on these human powered machines has quite an impact on our project. The ASME HPV competition requires its contestants to build a HPV that can not only compete on a speed course, but can also, with minimal adjustments or changes also compete in an endurance race. After minimal research, it became clear that the most popular design resembles a recumbent bicycle. Various designs include four wheel vehicles, as well as two and three wheel designs of various configurations. Popular two wheel designs include the Long Wheelbase (Figure 1), and Short Wheelbase-Under Seat Steering(Figure 2), while the popular three wheel designs include the Delta (Figure 3) and Tadpole (Figure 4).

Figure 4:Tadpole Trike

Over the past 10 years the HPV land speed record has been broken 9 times, all by HPV’s using the two wheel design. The current flying 200 meter land speed record is 81 mph, set at Battle Mountain, Nevada in October 5, 2002.

Using the prior work done to create the best modern HPV’s we can create a basic vehicle within our time frame and budget to meet our needs.

1.3.2. PatentsWe are looking at two different main HPV designs; three wheel (trikes) vs. two wheels.

Three Wheel HPV’s:

The basic components of the standard HPV can be found in the Patent entitled “Recumbent Tricycle” (patent number 4497502, patent date February 5, 1985). This basic HPV Trike uses a gear system to power the front tire, and uses a four bar mechanism to steer through the two rear wheels. The main shortcoming of this design is the steering system. From our research it appears that although effective at lower speeds the rear turning system is inclined to tipping at higher speeds, and for us to be competitive at the ASME competition we need to be able to turn without fear of rollover. Also, the three wheel system, while more stable when moving in a straight line, and easier to start from standstill, has a slower top speed then a two wheel recumbent which will be the next design discussed.

Figure 5:Standard Three Wheel Recumbent

Two Wheel HPV:

The two wheel HPV is the next main design that we are considering. Found in the patent titled “Recumbent Bicycle” (patent number 4,773,663, patent date September 27, 1988) the main design of a two wheel recumbent can be seen. Its shortcomings are found mostly in its difficulty to start from a standstill and to balance while riding and turning. Other then the model found in this patent (Figure 6), which places steering mechanism at the shoulder height of the rider there are also models the position the steering mechanism under the seat (Figure 7, patent number 4,283,070, patent August 11, 1981), which could provide a better ergonomic design.

Figure 6:Recumbent Bicycle with Overhead Handlebar

Figure 7: Recumbent Bicycle With Under Seat Steering

In all of these designs the short comings of a standard recumbent bicycle or tricycle are that they fail to meet our aerodynamic needs and their single crank gear system will not provide sufficient power and speed to compete with the other groups in the competition.

1.3.3. Codes and StandardsFor our human powered vehicle we will have to adhere to ASME welding and safety standards which focus on the safety of the rider by regulating wall thicknesses and roll bar specifications.

3. Concept Development

3.1. Overview

3.1.1. Creative Strategies During brainstorming we remained open and developed a diverse set of ideas. We broke down our designs into interchangeable subsystems. This strategy gave us separate designs for our drive train, braking, frame and steering which we then interchanged to create unique concepts.

3.1.2. Governing Principles The key principles that govern the functions of our HPV designs are:

Aerodynamics (wind resistance, frontal area, drag force) Biomechanics (Pedaling, torque) Vehicle Dynamics (Braking, Steering, Balance, Centrifugal forces) Solid Mechanics (frame stress, component stress) Machine Design (Drive train, gear ratios)

3.2. Synthesis and Analysis of Overall Concept

3.2.1. Overall Concept 1

Three Wheel Simplicity HPV

Our strategies to stay open minded helped us develop creative subsystems for this design. The layout for concept 1 is based off having a solid beam go from the wheel axe to the front tire fork (Figure 9). One of the unique subsystem designs is that the pedal system is directly attached to the front wheel, so that no drive train is necessary.

The advantages for this concept are that it would cut cost and there would be less complexity than other designs. Reasons for reduced complexity are that we won’t have a drive train and we eliminate a derailleur. The negatives of this reduction in complexity are that since there is no drive train there would be no shifting of gears so it would be tough to adjust speed or accelerate efficiently coming out of turns and we would lack speed. Another unique subsystem is our steering on this concept, it uses a U-shaped bar that goes under the seat and comes up to meet the riders’ hands about 12 inches from their chest. The steering is unique in that the bottom of the steering bar it has a bar on each side attached to the back axle to give us rear steering (Figure 10). Steering is a positive in that it would not be very difficult to construct and would not cost a great deal but the steering would not be ideal and could be unstable. Another negative to any three wheel design is

16

Page 18: Human Powered Vehicle CompetitionChris Jacobshome.sandiego.edu/~dmalicky/MENG491/Proposals/HPV…  · Web viewOver the next few pages we delve into the HPV world and show our progress

the added rolling resistance, weight, and frontal area, plus costs for extra materials. Advantages are that the vehicle that would spread the stress and has good overall stability to accommodate rookie riders. Braking system is very similar to any road bike in that it will use standard brake calipers and cables that attach on the steering bars. The aerodynamic design for this concept is small; a partial fairing would preferred be since we won’t be able to minimize the frontal area on a three wheel HPV.

3.2.2. Overall Concept 2

Two Wheel Cut and Gut HPV

The creative strategy for this concept came from minimizing cost, weight and complexity. This seems to be our most cost efficient vehicle concept because it is based on taking a modern steel road bike and augmenting it to become an HPV (Figure 11). The first step in the process is cutting the top bar at the seat stay and then cutting it again on the down tube about halfway down. These two cuts will be where the HPV seat will sit. A steel bar is then welded from the bottom cut to the old front fork and the old handle bar set up is weld back to the front of the frame. From there we add only have to add a front drive train and rewire the brake cables. Our drive train design is unique and provides the ability to switch gears which is very desirable to our design. We use the old gears from the double crank and attach another chain to the smaller crank that goes to the front of the HPV and connects to a single crank (Figure 12). Then a long partial fairing is attached to the horn shaped handle bars which provide our steering (Figure 13). The positives are that it would be relatively simple, low cost and it would have a high potential to perform well. This high potential comes from the fact that it has advantages in some key performance factors like weight, frontal area and rolling resistance. The negatives are that it lacks stability, and would require some difficult welds. The welding factor is also somewhat enlarged by the fact that we have a team of novice welders.

Figure 13: Steering Top view for Concept 2

3.2.3. Overall Concept 3

Three Wheel Tadpole HPV

Our creative strategies to keep options open also helped us come up with this three wheel design. This design was based on a desire for strong frame that would be ergonomically sound. The layout for this concept is one that relies on a sturdy frame and is adjustable for riders (Figure 14). The uniqueness of this HPV design is that it actually has two wheels in the front and it is the only concept that uses a single

19

Page 21: Human Powered Vehicle CompetitionChris Jacobshome.sandiego.edu/~dmalicky/MENG491/Proposals/HPV…  · Web viewOver the next few pages we delve into the HPV world and show our progress

chain for its drive train (Figure 15). These concepts are very nice because they provide great stability and will also give us the open undercarriage which makes it easy to install the drive train. Another interesting addition to this concept is the idea of individual steering bars for each wheel which makes it so that the HPV is easier for the rider to control and would be more forgiving on rider since it would take more effort to turn the vehicle (Figure 16). The seat lies on the frame of the back wheel and creates a more favorable angle for frontal area and ergonomics satisfaction. A few other positives that come in having this vehicle design would be the spread of stress and having good overall stability to accommodate novice riders. The aerodynamic design for the concept is going to be your basic partial fairing since we won’t be able to minimize the frontal area on this HPV design. A few disadvantages that come in to play on this three wheel design are the added rolling resistance, weight, and frontal area, plus costs for extra materials.

Figure 16: Steering top view for Concept 3

3.2.4. Overall Concept 4

Two Wheel High Profile HPV

The creative strategy to build this concept came about from our constraint on weight, with the idea to build a HPV that would be as light and reliable as possible. The back end of this HPV works much like a bicycle and has a full 8 speed cog set which goes onto a double crank (Figure 17). Like concept 2 it uses another chain to attach to the bottom crank and takes away the derailleur that would belong to that crank (Figure 18). This makes switching speed very painless and would provide a more efficient ride. From the backside fork the HPV transitions into the seat and main bar of the frame that connects to the front fork. Our steering subsystem then connects to the undercarriage of the design and uses a four bar set up to steer the front wheel (Figure 19). The fairing is then placed on the front side of the bike coming right over the pedals. Advantages of this concept are that it has a low center of gravity, gives us small frontal area, and it is light weight. Some disadvantages are that it is not the easiest to build and it would require the most work because it will be built from the ground up. Cost would also be relatively higher but those could be reduced by purchasing used bicycle parts.

3.3. Evaluation

After coming up with our various designs we wanted to develop a criterion to expose the best concepts. At first look all of our designs seem feasible and all have positives and negatives. We focused on eight different factors of different weights: rolling resistance, aerodynamics (frontal area), ergonomics, reliability, steering, cost, least complexity, and the weight.

3.3.1 Rolling resistance: A key factor in speed and endurance test so it was given a weight factor of 8.

Found that rolling resistance is directly proportional to the number of wheels of the HPV. This gives Concepts 2 and 4 an advantage since they have one less wheel; they are scored accordingly.

3.3.2 Aerodynamics (frontal area): Aerodynamics is the most important factor on our performance so we set its weight factor at 9.

We calculated the differences in frontal area and found minimal differences between both two wheel and both three wheel concepts. The results came to be 341 square inches for the two wheel designs and 455 square inches for the three wheel designs. This is a 4/3 advantage for the two wheel and is scored accordingly.

3.3.3 Ergonomics: Since we are essentially the only customers we felt this was important but not necessary to optimize so it has a weight factor of 4.

This part of the evaluation was based more on how we felt the design would feel to ride on. For example, concept 1 has the pedals in an awkwardly low position and the seat angle doesn’t seem ideal so it was given the lowest grade. Concept 3 by contrast sits in a nice riding position and puts the steering bars right into the riders hand without much discomfort so it received the highest score.

3.3.4 Reliability: This tests the longevity of our frame design and helps us decide how likely we are to break any joints so this got a weight factor of 8.

The scores for this section were decided based on the difficulty of the joints and the weight distribution along our HPV. So for this factor we looked at joint configurations that were more prone to fail and scored the different concepts accordingly.

3.3.5 Steering: This factor is important but not as key as others In that it would hinder the rider somewhat but is not a make or break subsystem, so it received a weight factor of 5.

For this factor we took into account front and rear steering while also considering the forgiveness of our steering designs. For example, concept 1 was worst in our assessment because it has rear wheel steering. Concept 3 was best for the steering because it allows for the most forgiveness which would be very useful in the 40 mile endurance ride. Concept 2 and 4 both had good steering but turn the bike very easily and are more prone to crashing, so they received intermediate scores.

23

Page 25: Human Powered Vehicle CompetitionChris Jacobshome.sandiego.edu/~dmalicky/MENG491/Proposals/HPV…  · Web viewOver the next few pages we delve into the HPV world and show our progress

3.3.6 Cost: Cost is solely based on how much money we anticipate each concept costing and how much materials that would be use to create the design.

Since Concept 2 is tearing down a standard steel road bike and recycling parts this design received the best score for cost. The worst score for any concept was concept 3 because of the amount of steel that and added parts.

3.3.7 Least Complexity: These scores were decided from anticipating part count and making an estimate of the amount of work and difficulty that would be required to build each concept.

This part of the evaluation rewarded concept 2 for requiring less building and hurt concept 3 for having so many parts. Concept 4 also did not score highly because of the difficulty in putting together subsystem like its drive train and steering configuration. Concept 1 has no drive train so that helped it but it still has a good number of parts and would require more time than concept 2.

3.3.8 Weight: The weight scores were calculated by doing a projection of weight based on amount of material and the added weight of subsystems.

Our calculations showed that concept 1 and 3 would be the heaviest with concept 1 being 8-12% lower in weight than concept 3. Our two wheel HPV’s scored the same since both had about a 33-36% reduction in weight when compared to the heaviest concept.

3.4. Refinements Our concepts all seemed to do well in our evaluation portion of this section but concepts 2 and 4 definitely stood out. This was due to high scores in the performance factors like rolling resistance, aerodynamics (frontal area) and the weight. The difference between these two concepts was very minimal and actually came out to be within 1 % of the highest score. Both concepts 2 and 4 have a high potential to do well in the competition but they also have significant weaknesses. Concept 2 for example has a significant weakness when it comes to reliability which enough reason alone to disregard the concept but it has a few huge pluses in that it is inexpensive, it is not complex and it’s light. One possible solution is to try and reinforce all the joints so that none of the joint can fracture. This would add

weight, complexity and cost but would eliminate a glaring weakness. The only real issue with this solution would be that it may produce something that was not too aesthetically pleasing. Another significant factor is that the double chain design would not be preferred and using concept 2 we would be committed to that drive chain design. Concept 4 doesn’t really have major weaknesses but it doesn’t have idea steering and it is somewhat complex. A good solution for this issue would be to change the steering subsystem to something that was better and less complex. This concept is also much more robust than concept 2 and allows us to switch the change drive train to the single chain design we saw in concept 3. Another issue would be the high rolling resistance on such a small front tire but since we have room to play with on the fork that can be easily adjusted.

Key adjustment:

Single Chain Drive train Resize of front fork and front wheel Adjust frame angle to accommodate new front fork size

3.5. Selection

Concept 2 and 4 both scored very well but because Concept 4 was a more robust design we decided that it would be our choice. This concept allows us the flexibility to switch any and all subsystems and gives us greater potential to succeed in the HPV ASME competition.

4. Design Specifications

4.1. Design Overview

4.1.1. DescriptionThe overall vision for our project is to build an HPV that is a skeleton recumbent bicycle using a two wheel design, which will decrease weight, increase speed so that we can be competitive in the speed portion of the competition. Our seat will be composed of a material fabric placed in the rear third of the HPV to provide rider comfort and decrease weight for the endurance race. We will be using steel stock tubing for a variety of our HPV components; our frame will connect the front wheel to the body of the HPV, which will be a square frame to support the rider and his seat and then two sections of tubing will be used to connect the seat frame to the back tire. The drive train will be a single chain multi-gear system that will allow us to obtain our top speed as well as navigate the endurance course. The system will be powered by our rider using pedals attached to the gear system similar to a modern bicycle. An aspect of our vehicle that was not addressed in our concept discussion but is still very important, are the tires that we will be using. Our research to determine what tires to use indicated that our desired tires could be interchanged regardless of HPV concept. Therefore, to ensure that we would not have to worry about tire issues mid-race and to achieve the best performance from the tires themselves we chose Kevlar reinforced tires as the optimum choice.

Page 27: Human Powered Vehicle CompetitionChris Jacobshome.sandiego.edu/~dmalicky/MENG491/Proposals/HPV…  · Web viewOver the next few pages we delve into the HPV world and show our progress

Our overall HPV design will consist of four separate subsystems; the drive train, the braking system, the HPV frame and steering system. Each of these systems are incorporated into all of our designs although their configurations change over these different designs. The aspects have the drive train have already been reviewed in the prior paragraph. The braking system will utilize standard brake pads on both the front and rear tire and be initiated using traditional handle brake triggers. The HPV frame will be constructed out of steel stock as previously stated, and will be the first section constructed. Our steering system will be composed of a four bar mechanism connected to the front wheel fork. This system will be an undercarriage system that sits directly beneath the frame and the seat rather than the overhead design of a traditional bicycle.

The most important design aspect that correlated with our customer requirements will be the safety constraints. ASME needs to ensure the safety of the drivers, and to meet these standards we have included it as a part of our design specifications and a top priority. Similar items of importance are braking and turn specifications. ASME provided specific specifications that we must adhere to; i.e. braking to a complete stop from 20 mph within 15ft as well as navigating a turn of radius 25ft. To achieve these needs we will have to build these capabilities into our HPV design.The hardest specification that we will have to accomplish is our speed specification. We want to reach and maintain a top speed of 30 mph for the 100 meter speed race. A max speed requirement is not given by the ASME guidelines, however, to be competitive in the speed race we will have to achieve at least that speed. We will be relying on the drive train to achieve this goal. The only design specification that we may need to neglect is the fairing system which affects the aerodynamics of the HPV. It will be the most difficult to accomplish because of the cost of materials as well as our lack of knowledge on the subject. Also, we do not have the tools or funding to create a fiberglass (or other comparable material) fairing, so this aspect of the design may be cut or just simplified to a 2D form.

4.5. Subsystems Drive Train:

We will include a multi-gear one chain system that is attached to the back wheel to transmit power. It will act identically to a standard bicycle.

5. Project Plan

5.1. ResearchThere are four areas on which we will require more research; these are the gear system, the steering system, the HPV’s tires and the fairing options. While we have already obtained much research on these aspects, we still do not have enough information to create a workable design. For the gears; we need to learn more about gear ratios to determine what types of gears we would like to use on both the endurance and speed races. This information will be important because it will determine the overall design of the HPV because we must account for the space our gear system will occupy. We must do more research on our steering mechanism because while we have already committed to the undercarriage design, we are not certain it is the best design for what we are trying to accomplish. Our main questions revolve around its affect on the stability of the HPV and its ergonomic impacts.

We have done very little research when it comes to tires and what we want to see used on our HPV. There are a wide variety of options for us to choose from and we must weigh all of our options. We need to find a tire that will not use to much of our energy to overcome friction forces, but we don’t want a tire that slips on the pavement. We need a tire that is light so that we can still have a fast moving HPV, but one that is durable enough to handle the endurance course. These specifications are areas that we need to still look into and analyze. Finally we need to do more research on fairings, because we still do not really understand what they do other then make our vehicle more aerodynamic. We do not know how or where to mount them, and we also have limited knowledge about what types are the best for our budget and what we want to do with it. Before we can put any more thought into the overall design these are questions that we must have answered.

5.2. Critical Function PrototypesThe critical functions that we have to analyze are the gear system, the braking system, the steering system, and the safety of our HPV. All of these critical functions are straightforward to analyze and a standard analyses of each will be sufficient to provide us confidence in each area.

5.3. DesignOur design process seems as though it would be unique to that of our peers. We are not creating something that is new or has not been done. In essence or creation is a collection of ideas that would best fit for what we are trying to accomplish. We will be using computer tools such as Pro Engineer Wildfire but it will be used to show a 3-Dimensional layout of our design, not to give an analysis of our design.

Our first step in the process to create a successful design was to research what design had been previously successful. The idea behind this was to try not to develop a design that was not

32

Page 34: Human Powered Vehicle CompetitionChris Jacobshome.sandiego.edu/~dmalicky/MENG491/Proposals/HPV…  · Web viewOver the next few pages we delve into the HPV world and show our progress

realistically feasible. It also helped give us a general idea of the complexity of our project so that we could more easily gauge what our HPV would cost and how long it would take to build it.

Before we could fully develop our design we had to figure out what would build and what we would be purchasing. We figured wheel sets; braking system and our steering system would be purchased and would be mounted onto our design. Our gear set will also be purchased but we will have to be creative with that and create our own design with what we by so that it fits our frame design. The frame set will take on the majority of the complexity. We also felt that it would be a good idea to purchase the fiber glass faring since we lack the resources to be able to create our own design to specially fit the design of our HPV.

Looking at the design of our frame we wanted to build something that would be very sturdy while also not being too heavy so that it won’t slow us down in the endurance and speed competitions. This issue will be our primary design trade off and will need a bit more research in order to find the best balance for our HPV. Our biggest worry with any design would be the joints on the frame since we would need to weld those by hand and none of us have a more than a couple hours of welding experience. We also would need a very strong front fork, since any recumbent vehicle would put a lot of strain on the front end of the vehicle.

Most of our subsystems interactions are made to be relatively simple so that we focus on making sure our HPV can meet the requirements. Our brake system will be very basic and will be mounted much like any modern bicycle, where they mount to the fork on the front end and for our back brakes we will mount it off the frame. Our steering system is somewhat unique and will look much like standard handle bars but it will be mounted backwards on the undercarriage of our HPV and will steer using cables attached to the top of the front fork. Our gear system will be very creative but doesn’t seem to be too complicated. It will attach to the back tire and look much like any normal 8 speed, double crank bicycle but the kicker is that it won’t have a front derailleur but instead on the small crank we will attach a long chain that will go under the undercarriage and attach to our front crank that will be rotated by the pedals.

There will be some manufacturing difficulties that may arise when we are welding the frame together but those issues have yet to arise. Some of our objectives would be to minimize frame weight and we would like to optimize joint strength. We would also like to maximize our gear ratio for our gear system and as far as the estimated time to complete the design of each subsystem please see our Gantt chart below.

5.4. ConstructionWe will begin the construction of our HPV with its frame. This is the main component of our design and must be built first so that the other systems can be built off of it. We will be purchasing rectangular steel stock and steel tubing to create the frame. There will be one main portion of the frame where the seat frame will be attached to. The seat frame will be welded onto the main frame. The triangle frame for the back tire will also be welded onto the main frame. For the front tire we will be bolting a fork tire frame to the front of the main frame. A majority of the frame will be welded together with very few bolts used to old pieces together. All of the frame will be built and welded in Loma 4. After the frame is

33

Page 35: Human Powered Vehicle CompetitionChris Jacobshome.sandiego.edu/~dmalicky/MENG491/Proposals/HPV…  · Web viewOver the next few pages we delve into the HPV world and show our progress

created we will be adding the gear system and wheels. The gear system and wheels will both be purchased by vendors and we will install them. The gear system will consist of gears, chains, and pedals, and the back wheel will be larger than the front. We will connect the pedals and wheels using bolts, while the gear box will be welded to the main frame. After installing the wheels and gears we will install the handlebars and brake system; these systems will also be vendor purchased. The handlebars will be an undercarriage style that uses a four-bar mechanism to rotate the front tire. The four bar mechanism will be created out of our rectangular stock and connected using bolts and pins to both the handlebars and the front tire fork. The handlebars themselves will be attached to the main frame using bolts. The brake will be attached to the handlebars similar to a bicycle design, although for HPV the brakes will only be attached to the front tire. After adding the brake system and the steering system we will install the seat cushion. The cushion will consist of a foam bottom and a thin material backing. The backing will be attached between two steel tubes as a portion of the seat frame and the cushion will be screwed into its portion of the seat frame. To protect the rider, the roll bar and safety belt will be installed. The roll bar will be welded together out of our steel stock and placed directly over the seat to protect the rider in case of an accident. The safety belt will be modeled after those found in the drivers and passengers side of cars as specified by the ASME rules. Finally we will add the fairing as our last component of the HPV. It will be screwed into the front portion of the main frame and if necessary we will extend it over the sides of the HPV using sheet metal which will be attached with bolts and spot welds.

5.5. TestingTo test our HPV we will have to have it completely assembled for all but one component. The only component that can be tested without being assembled is the gear system. If it is set up properly on a rig in one of the labs we can use a tachometer to determine if the gear translates its rotational speed to the tires, and although this will not be extremely accurate without the weight of the rider and the friction of the road it will give us a general idea of what will occur. To test the rest of our components the vehicle must be assembled. To test the speed portion of our bike we will have to head out to Fiesta Island which will provide us with a safe and isolated area that is close in proximity and has a location that will very closely mirror the track that we will have to compete on in the competition. There is a long stretch that will allow us to test how long it takes and how long we can hold our top speed, as well as our stopping time from that speed. To test the steering we will be able to use the Loma parking lot. The ASME rules state that we must be able to maneuver through a turn with a radius of 25 feet. In the empty parking lot we will have a safe environment which will allow us to test the turn radius of our vehicle at various speeds. To test the set braking parameters that the ASME guideless provides us, we must return to Fiesta Island. The rules state that we must be able to stop with 20 ft if going 15 miles per hour. By using Fiesta Island we eliminate unnecessary obstacles and have a way of gauging speed by driving a car next to the HPV. When testing our endurance components of the HPV we just need to ride the vehicle for extended periods of time, and the local areas provide plenty of options to do that. BY driving for extended periods, we become more comfortable with the handling of the HPV which will help us for the competition, and it will also provide us with instant feedback in terms of stability and ergonomics which we otherwise might not notice until the last minute. Finally, our last and most important test specification would be the safety factors. To test these would have to make sure that the

34

Page 36: Human Powered Vehicle CompetitionChris Jacobshome.sandiego.edu/~dmalicky/MENG491/Proposals/HPV…  · Web viewOver the next few pages we delve into the HPV world and show our progress

roll bar and safety harness protect the rider from dangers that would occur if there was an accident. To do this we would place the HPV in positions that would occur during an accident and see if the rider would either hit the ground or be harmed in some way. Examples would be to lay the HPV down on its side or even upside down and see if the roll bar and seat belt keep the rider in place. Also, by putting the HPV in different positions to simulate accidents, it would also provide us with more insight on how to make our vehicle even safer.

5.6. Project DeliverablesAt the end of the second semester our project deliverables will be:

Final Design Report including test resultso We will have a design report that will show the development of our project in its

construction phases. It will name all design changes made during this time as well as clearly demonstrate our test methods and results. It will also contain the results from the ASME competition

A working prototype that meets customer requirementso We will have a prototype that will have competed in the ASME HPV competition and

will have met all of the ASME requirements. Analysis of any failed components

o Most failed components will have an in depth analysis, however, to conserve materials and funding most parts will be reused, unless they are broken or excessively damaged in the process.
