COMPARISON OF OPERATING PERFORMANCE OF SEMI-ACTIVE USED MAGNETORHEOLOGICAL DAMPER AND PASSIVE SUSPENTION SYSTEM FOR QUARTER VEHICLE MODEL

Abstract

The ride comfort of a vehicle depends on the structure of suspention system,
characteristics, intensity of excitation and control technique. Suspension system plays
an important role in ensuring driving comfort and stability. Today, semi-active
suspension with good performance and low production cost has been widely adopted
by many car manufacturers and the results of testing have many advantages over the
system. This paper presents the results of research and application of Matlab / Simulink
software to simulate and evaluate semi-active suspension dynamics using magnetic oil
damping. The results show that the dynamic characteristics of the semi-active
suspension are better than that of the passive suspension.
