Abstract: The hydro-pneumatic semi-active suspension system consists of a damper with variable damping coefficient and parallel coil spring. This paper is concerned with the studying the performance of hydro-pneumatic semi-active suspension system theoretically predicted using two degree of freedom of quarter car model. The theoretical results are generated when the system is excited by random road input. The damping coefficient of the hydro-pneumatic damper is taken from the experimental to predict the results. Finally the results are given and analyzed.
