摘要：

According to the generalized Ruzicka vibration isolation model for high-speed train vertical vibration with or without considering the wheelset vibration displacement, through equation transformation, the high-speed train vertical vibration state space expression that is convenient for numerical integral was established. Based on this, using random vibration theory, the vertical vibration characteristics of high-speed train were studied, and the differences between the two models were analyzed. Based on the generalized Ruzicka vibration isolation model of high-speed train vertical vibration considering the wheelset vibration displacement, the influence of damper parameters on the dynamic response of train was analyzed. With vehicle body vertical vibration acceleration, vertical travel of secondary suspension, bogie vertical vibration acceleration, and primary suspension travel RMS as the target, using the evaluation function method, the optimization method of damping parameters of high speed train vertical damper was built. Through analysis and comparison, the results show that the optimization method can further improve the running quality of the train, and provide a useful reference for the selection of the damping parameters of the vertical damper of the high-speed train. © 2019, Department of Journal of the China Railway Society.
