VEHICLE DYNAMICS
This project was performed as part of the coursework meeting certain industry standard requirements.
BRAKE DIAGRAM:
- Front application pressure is the reference. The rear pressure is limited by using the proportioning valve. The proportioning ratio is mentioned in the figure.
- Front and rear brake forces are computed
- Deceleration is then calculated knowing the total weight of the vehicle (in terms of g)
- Front and rear axle loads are then calculated
- Braking co-efficients and braking efficiency are accordingly computed and graphed
2 ITERATIONS ARE PERFORMED to satisfy
- FMVSS 105 second effectiveness
- FMVSS 105 third effectiveness
All figures are created on MATLAB.

Iteration 01:
Sanjiv Valsan-Brakediagram-iteration 01
Sanjiv Valsan-brakingcoefficient-iteration 01
Sanjiv Valsan-decelerationcurve-iteration 01
Sanjiv Valsan-efficiencycurve-iteration 01
Iteration 02:
Sanjiv Valsan-brakediagram-iteration 02
Sanjiv Valsan-brakingcoefficient-iteration 02
Sanjiv Valsan-decelerationcurve-iteration 02
Sanjiv Valsan-efficiencycurve-iteration 02
Depending on the road condition, the proportioning ratio can be changed for different brake diagrams. Accordingly front and rear brake pressure varies and braking occurs. Both the iterations are graphed against each other as well.
