Mr Damper And Its Application For Semi-Active Control Of Vehicle Suspension System, G Z. Yao, F F. Yap, G Chen, Weihua Li, S H. Yeo

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, a semi-active control of vehicle suspension system with magnetorheological (MR) damper is presented. At first a MR damper working in flow mode is designed. Performance testing is done for this damper with INSTRON machine. Then a mathematical model, Bouc–Wen model, is adopted to characterize the performance of the MR damper. With optimization method in MATLAB^® and experimental results of MR damper, the coefficients of the model are determined. Finally, a scaled quarter car model is set up including the model of the MR damper and a semi-active control strategy is adopted to control the vibration of …
