一、车辆振动试验台的任务试验研究的目的是验证理论分析的结果,同时又把试验中发生的各种现象上升到理论分析。车辆在运行过程中的振动是很复杂的,只进行理论分析是不够的,必须要有一定的试验数据。但是在铁道线路上的试验要受到地点、时间和经费上的很大的制约。因此最现实的方法是把线路运行试验的大部分项目由试验台来承担,而在线路或试验线上进行最后的修正试验。试验台试验的一个很大优点就是能够单独地或组合地自由复现车辆在线路上运行中的复杂过程,这一点是很必要的。当然在试
First, the task of vehicle vibration test bench The purpose of the test is to verify the theoretical analysis of the results, at the same time, the phenomenon occurred in the test rose to the theoretical analysis. Vibration of the vehicle during operation is very complicated, only theoretical analysis is not enough, we must have some experimental data. However, tests on railway lines are subject to great constraints in terms of location, time and funds. Therefore, the most realistic method is to take most of the items of the line running test from the test stand and perform the final correction test on the line or test line. A great advantage of the test bench test is that it is necessary to be able to freely reproduce the complex process of running the vehicle on the line, either alone or in combination. Of course, try
