摘要：
According to the 9 degree-of-freedom hunting motion vibration model of bogie, by analysis of vehicle running stability and using the Hurwitz stability criterion, a mathematical model of yaw damper damping coefficient based on running stability is established; according to the vehicle derailment safety when vehicle drives on the curve track, a mathematical model of yaw damper damping coefficient based on curving performance is established. Based on this, using the golden-section adaptive, the compromise optimization design method of yaw damper in stability and curving performance is built, and its main influencing factors are analyzed. With a practical example of high-speed train, the optimal damping coefficient of yaw damper is designed and validated by simulation. The results show that the damping of yaw damper designed can make vehicle have good running stability and curving behaviors, thus, the optimal damping matching theory and design method of yaw damper for high-speed train is correct. © 2018 Journal of Mechanical Engineering.
