Comparison of a 10 DOF quarter vehicle model with the FE analysis of tire impact against a road

In order to investigate the dynamic behaviour of tires on extreme irregularities on the road, a 10 degrees of freedom lumped 2D quarter vehicle model, comprising the two point rigid ring follower tire model, is presented and implemented in Matlab Simulink. The simulation results of tire impact against a step on the road, at various speeds and step heights, are compared to the results achieved by the FE analysis of the same problem.
