Abstract: This paper presents the simulation of a semi-active suspension system by using designed parameter model of magnetorheological (MR) damper. The design is based on the performance of the original equipment shock absorber of a passenger vehicle. A 7DOF of vehicle ride model was developed and validated in order to study the performance of a passive suspension system and the designed semi active suspension system. A controller known as modified skyhook algorithm and current generator model was used in the semi-active suspension system. The simulation results show that the semi active suspension system give significant improvement on vehicle|s ride comfort.

Keywords: magnetorheological damper; ride performance; modified skyhook; semi-active suspension system; current generator model; vehicle ride; simulation; parameter modelling; shock absorbers; passenger vehicles; passive suspension; vehicle suspensions; ride comfort.
