Quarter car automotive suspension model is the model with two degrees of freedom system, which is used for the analysis of ride comfort and vertical movement of the vehicle. It represents the analysis of vehicle suspension system at any one wheel out of all four wheels; it means the vertical motion of the vehicle body at any one wheel of the vehicle is being analyzed to check the performance. Automotive suspension designs have been always compromise between road handling, road holding and passenger comfort. This paper describes the dynamic model of quarter car automotive suspension system for bump condition prepared in MATLAB using Simulink. The influence of varying values of tire stiffness on vertical acceleration of the vehicle has been discussed in this paper. The results obtained from the simulation of simulink model are used for performance investigation and analysis of the dynamic behavior of the vehicle.
