The research on the lateral semi-active control of high-speed trains is mainly aimed at improving the lateral running stability of the train body.However, after the improvement of its lateral running stability, the interaction between it and various components often leads to the intensification of the transverse vibration of the frame and the transverse action of wheel and rail, which increases the derailment coefficient and makes the safety performance of the train worse.In order to solve this problem, this paper puts forward the virtual inertial damping semi-active control algorithms and derailment semi-active control algorithm on the basis of the two control circuit design of multi-objective constraint hybrid semi-active control algorithm: at the same time of train transverse semi-active control, avoid derailment coefficient increase, and at the same time improve the comfort and safety.A multi-rigid-body dynamics model of a high-speed train was established by using Simpack, and a co-simulation analysis system was established by combining Matlab/Simulink.The results show that, compared with the semi-active control algorithm of virtual inertia damping canopy, the semi-active control algorithm of multi-objective constraint can not only effectively restrain the transverse vibration of the vehicle body, but also improve the lateral running stability of the vehicle body and improve the level of train stability.Moreover, it can effectively reduce the derailment coefficient and improve the safety of train operation.
