机车车辆动力学试验线况识别的方法

Method of Identifying the Line State for Locomotive and Car Dynamics performance

在机车车辆动力学性能试验中 ,必须考察评价被试车在各种不同的速度、线况下的动力学性能 ,为此在动力学试验中必须采集线路状况。对目前采用的各种线况采集方法进行了分析比较 ,指出了它们的优缺点 。

In the locomotive and car dynamics test,the dynamics index should be considered in the case of varying speed and line state,so the line state should be acquired in the dynamics test.This paper introduced some method of identifying the line state,their merit and shortcoming were putted forward,and their using range were suggested.
