确定车辆系统线性和非线性临界速度的新方法

A New Method to Determine Linear and Non Linear Critical Speed of the Vehicle System

将车辆速度视为时间的慢变参数 ,提出了一种近似计算线性临界速度、非线性临界速度和极限环的数值方法 ,该方法亦可对机车车辆蛇行稳定性的滚动振动试验台试验起到指导作用。以一高速客车为应用实例 。

With the vehicle speed regarded as the slowly changing parameter,a numerical method with which the linear critical speed,non linear critical speed and the limit hoop are calculated approximately is given.The method can also play a guiding role in the rolling and vibration test stand testing for hunting stability of rolling stock.With a high speed passenger car as a practical example,the parameters of the linear critical speed and non linear critical speed are researched.
