摘要

This paper is aimed to show the feasibility for improving the ride quality of railway vehicles with semi-active suspension systems using magnetorheological (MR) dampers. A nine degree-of-freedom railway vehicle model, which includes a car body, two trucks and four wheelsets, is proposed to cope with vertical, pitch and roll motions of the car body and trucks. The governing equations of the railway vehicle suspension integrated with MR dampers are developed. To illustrate the feasibility and effectiveness of controlled MR dampers on railway vehicle suspension systems, the LQG control law using the acceleration feedback is adopted, in which the state variables are estimated from the measurable accelerations with the Kalman estimator. The responses of the car body under random track irregularities and periodical irregularities with MR dampers are evaluated and compared with the cases without control. The simulation results show that the vibration control of the train suspension system with semi-active controlled MR dampers is feasible and effective.
