Abstract

According to the analysis for magneto-rheological (MR) damper´s working mode, structural optimum design and magnetic circuit analysis are completed on automobile MR damper. Test was done in the designed MR damper on the MTS850 damper testing machine, indicator diagram and characteristics of MR damper were measured by change the piston´s velocity and input current. A polynomial model is fitted and the damper´s machine model can be established accurately by using experimental data. Based on the research results, it will be easy to real-time control for semi-active suspension.
