Design Validation Plan

Sub Systems Test Description Resources Procedure Acceptance Criteria

Engine Top Speed Chassis dynamometer

Vehicle is run at top speed and speed from tachometer is noted

Vehicle should attain a minimum speed of 80kph

Braking Braking Distance Measure Tape The vehicle is run at top speed and both normal braking and panic braking conditions are rehearsed

Vehicle should stop within a distance within 30m

Steering Turning Radius Measure Tape Taking outside tire impression while making an o-shaped turn

Should at least have 4m

Maneuverability Slalom Test Track Slalom cones are placed 10m apart The vehicle must negotiate the track

Lock to Lock Angle Magnetic base Angle Finder

The Steering wheel is rotated from one end to another to obtain lock to lock angle.

The lock to lock angle must be 1280°

Suspension Suspension Travel Spring Compression Testing Machine

Spring is compressed to its solid length Required spring constant is verified

Ride Comfort Pebble Track Vehicle will be run on track with pebbles to ensure proper ride quality in rumbles

Suspension intact , Low Bump steer

Ergonomics Field of Vision And Reach Driver The driver is seated and personally checks for comfort and visibility

Driver comfort enough to race a 2 hr long race and field of vision of 210 degree
