A new semi-active combination control is proposed in this paper, and the problems from semi-active lateral damper (SLD) control and semi-active yaw damper (SYD) control can also be solved. Firstly, a 300 km/h Electric Multiple Units (EMUs) dynamic model is built, and parameterized SLD and SYD models are achieved. Secondary, the semi-active control strategies are realized in SLD and SYD model, and some curve-passing conditions of EMUs are simulated. After comparing the two control results, SLD control can improve lateral ride index of vehicle but the safety index, and SYD control can improve safety index but the lateral ride index. Finally, a new SLD-SYD combination control strategy is proposed and applied in EMUs model. The simulation results show that the new control strategy can solve the problems above, and improve safety index and lateral ride index at the same times.
