Air Bearing System & Layout Review

Agenda

Desired Outcome of Review

Systems Design using Air Bearings

Fixed System

Free System

Air Skid Research

DECISION for design direction

Layout Review

Review of Weighting Results

DECISION for design direction

Desired Outcome Decisions for the air bearing system

Pursue chosen design as the main mechanical design component for

the remainder of MSD II

Layout decision

Finalize high-level design and dive into detailed design based on

design aspects chosen to be pursued

Time Line

Customer Needs Review

Relaxed

From beginning of project (December 2012):

Free Slave Frame System

Pros Cons

Does not require permanent

station fixtures

Stays with compressor through

entire assembly

Set at working height of 18”

Can be bolted to floor for

testing

Requires level movement pathway

More complex frame design

Requires bolting into floor or substrate

Must be removed for shipping

2 Frame Models necessary (MOS/HOS and HOSS)

Compressor frames must be pre-painted

Ergonomic issues regarding beam width

Step 1: Compressor frame is loaded

onto free slave frame system

Step 2: Air pallet is slid into the fixture

using integrated free rolling casters

Step 3: Air pallet inflates and allows

movement to next station

Step 4: Assembly moves to next station

Fixed Slave Frame System

Pros Cons

Eliminates the need to level a pathway down the length of the line

Reduces the slave frame(s) down to single horizontal beam(s)

Posts will be embedded level and flat in the floor to eliminate need for leveling

Fewer air lines under unit

Beams can be anchored to test bed for test- do not need to remove from frame

Requires fixed extrusions in the

floor

Can now only set the

compressor down at designated

stations

Step 1: Horizontal beams are placed

on the loading station

Step 2: Compressor frame loaded is

onto and fixed to horizontal beams

Step 3: Air pallet is slid into the fixture

using integrated free rolling casters

Step 4: Inflation of the air pallet lifts

the horizontal beams and compressor

frame free of the fixture, allowing

movement to the next station.

Air Platform Sizing

Air Platform Sizing

The Movable Air Platform will be a minimum of 34” wide

Actual available dimensions are pending, possibly larger

Length of Air Platform is dependent upon unit to be moved

Layout Design 4 layout designs The team created 2 straight line and 2 U-shaped process layout designs. Several detailed factors and

rankings were given to help enhance design selections.

Feedback Factors and ranking weights

Operator feedback

People flow

Parts flow

Inventory Capacity: 2 days vs. 7 days

Floor modeling of layout

Ability to narrow down areas of major concern and improvements

Straight Line vs. U-shaped process design

Compare/contrast between layout designs
