摘要: 根据转向架9自由度蛇行运动模型,通过车辆运动稳定性分析,利用赫尔维茨稳定判据,建立基于运动稳定性的抗蛇行减振器阻尼系数解析计算数学模型;根据车辆通过曲线轨道时车辆脱轨安全性的要求,建立基于曲线通过性的抗蛇行减振器阻尼系数解析计算数学模型;在此基础上,利用黄金分割法,建立基于运动稳定性和曲线通过性折中最优的抗蛇行减振器阻尼系数解析设计方法,并对其主要影响因素进行分析。通过某高速客车抗蛇行减振器最优阻尼系数的设计实例、仿真分析及可靠性验证,可知所设计抗蛇行减振器阻尼能够使车辆具有良好的运动稳定性和曲线通过性能,结果表明,所建立的高速客车抗蛇行减振器的阻尼匹配设计原理和方法是正确的。

Abstract: 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.
