Mathematical Modelling and Simulation of a Simple Quarter Car Vibration Model

A vehicle suspension system is required to improve ride comfort and road handling. In current article it is simulated and analyzed the handling and ride performance of a vehicle with passive suspension system, quarter car model with two degree of freedom. Since, the equations of the system can be solved mathematically a scheme in Matlab Simulink and also in state space has been developed that allows analyzing the behavior of the suspension. The scheme that was created in Matlab Simulink, can be introduced excitation signals, this case a step signal.
