铁路车辆动态性能的试验模拟与分析

The Test Simulation and Analysis of the Dynamic Characteristics of Rolling Stock

应用多通道激振试验系统，采用“阻抗矩阵”对铁路车辆的动态性能进行试验模拟，可再现车辆在线路上运行时的状态。利用模拟试验和振型试验，测试和分析车辆各部振动的相关性和传递函数，确定车辆振动特性、固有频率和阻尼，可对车辆的振动性能作出评价。

With the application of multichannel vibration exciting test system and the Impedance Matrix Method, the simulation test of the dynamic characteristics of rolling stock is made. which can reproduce the operation stute of rolling stock on rail. The simulation test and vibration mode test are used to test and analyze the vibration correlation among the parts of rolling stock. to test and analyze the transfer function, to determine the vibration characteristics. inherent frequency and damping of rolling stock. Hence.the vibrating performance of rolling stock can be evaluated.
