| 摘 要： | 随着列车运行速度的提高,高速客车横向稳定性一直是近年来研究的热点. 建立 9 自由度半车数学模型,利用数值方法对该系统的横向稳定性与分岔问题进行了研究,得到车辆系统发生蛇行运动时的临界速度及分岔后各运动状态的转变过程. 结果表明系统超过临界速度后会发生复杂的动力学行为,包括单周期、两周期、混沌运动等,并且由对称向不对称,最后再向对称运动转化.

| Abstract: | With the development of the train＇ s speed, the lateral stability of high-speed passenger car is search focus in recent years. A mathematical model of half railway vehicle model is established with 9 freedom. Numerical method is used to study the system＇ s lateral stability and bifurcation problems, the speed and transition proeess of motion state are obtained. The results indicate that some complex dynami the redegree critical cal behavior included simple periodic, two periodic, chaotic motion and so on are existed, and it changes from symmetric to asymmetric, finally changes into symmetric motion, which are found beyond critical speed. |
