Title: STUDY ON CONTROL OF A VEHICLE SUSPENSION SYSTEM BASED ON MAGNETORHEOLOGICAL DAMPER
Abstract: The semi-active control of a quart-car model is studied and an improved Bingham model is proposed to describe damping force of a magneto-rheological(MR)damper.The effects of all physical parameters on the amplitude-time curves of the model are studied so as to control the system resonance effectively.Finally,the comparison of the vibration control effect among using traditional damper with passive control,MR damper with passive control and MR damper with semi-active on-off control in frequency domain is performed,it shows that the semi-active nonlinear on-off control can remedy the deficiency of the nonlinear passive control and have a good performance in vibration control when the system is in its resonance region or at high frequency region.
