Simulation study of the Magnetorheological Fluid damper in the semi-active suspension system

This paper first describes the working principle of vehicle Magnetorheological Fluid shock absorber. Then, the mechanical model of magnetorheological fluid (MRF) damper and passive damper were established and analyzed using simulation method, respectively. The result shows that the MRF damper can eliminate the resonance peak, reduce the natural frequency of the system and improve vehicle comfortability.
