With the increasing speed, the vibration control of high-speed railway vehicle suspension system becomes more and more important. In view of the nonlinearity of high-speed vehicle and the time-delay problem of control system, a new intelligent material magnetorheological damper (MRD) is introduced. On the basis of analyzing the dynamic characteristics of MR damper, a vertical dynamic model of high-speed railway vehicle system based on MR damper is established. In order to suppress the vertical vibration of suspension system, a preview-fuzzy control strategy based on MR damper is proposed. In order to verify the availability of the control strategy, a lot of simulations are carried out. The results show that the preview-fuzzy control strategy based on MR damper can effectively reduce the vibration amplitude of the suspension system and solve the problem of time delay to a certain extent.
