Importance of Pitch Compensation and Selection of ARB and Springs

Springs and Anti roll bar plays a vital role in the performance of the vehicle , as Anti roll bar is used to resist the rolling action of the vehicle and springs are used to isolate the sprung mass from the road disturbance. These two components are selected based on the mathematical modelling of the vehicle parameters, for this you should understand all the suspension parameters and its significance. The ride frequency optimization is done to avoid the pitching effect of the vehicle, when it undergoes a bump, in this project you will plot the bump oscillation profile and tune the vehicle parameters accordingly. As a result of this project , you will get to know how to analyse the vehicle loads at various hard points and spring rate and ARB diameter will be found to get the optimized result.
