This paper is mainly discussing about the mathematical modelling and simulation study of two degree of freedom quarter car model. The state space mathematical model is derived using Newton’s second law of motion and free body diagram concept and the vehicle body along with the wheel system is modelled as a two degree of freedom quarter car model. The performance of the system will be determined by computer simulation using MATLAB/SIMULINK. Passive, semi-active and active suspension systems connected in a single loop and tested under step and single bump input.
