With the continuous improvement of high-speed railway train operation speed, the problems of train operation safety and wheel rail wear are increasingly prominent. Improving train safety and reducing wheel rail wear can reduce operation and maintenance costs and bring greater economic benefits. In this context, a new semi-active control strategy applied in a Magnetorheological damper (MRD) is proposed to improve train safety and reduce wheel rail wear. Firstly, the transmission characteristics of the vehicle are analyzed according to the lateral vibration model of one quarter of two degrees of freedom. Then, the co-simulation model of Universal Mechanism (UM) and MATLAB is established, and the proposed control strategy is applied to the model to study its impact on the dynamic performance of the train. At the same time, the paper analyzes the influence of the control strategy on the dynamic performance of the train under different wearing levels. The results show that the control strategy can reduce the derailment coefficient of the train and the lateral force of the wheel axle, and improve the safety of the train greatly. At the same time, the wheel rail wear is reduced, the wheel wear degree is reduced, and the lathing cycle is prolonged. In addition, the control strategy can take into account the ride comfort of the train and maintain the good operation quality of the train.
