某动车车辆台架动力学性能试验研究

Experimental Study on Dynamic Performance of High-speed Vehicle Platform

以某高速动车车辆为研究对象,将其放置在转向架滚动振动试验台进行相应的动力学性能试验,研究同种抗蛇形减振器在车体与转向架构架之间不同的布置方式对车辆运行稳定性的影响。研究结果表明:抗蛇形减振器采用的不同布置方式对车辆稳定性有较大的影响。在进行转向架设计时,不仅要合理选用抗蛇形减振器的性能参数,同时要选择使车辆更稳定的抗蛇形减振器布置方式。

With a high-speed bullet train as the research object,the corresponding dynamic performance test was carried out by placing the train on the bogie rolling vibration test bed,and the influence of different arrangement modes of the homologous anti-snaking shock absorber between the car body and bogie frame on the running stability of the vehicle was studied.The results show that the different arrangement of anti-snake shock absorber has great influence on the stability of vehicle.In bogie design,therefore,the reasonable selection of anti-snake shock absorber performance parameters as well as the anti-snake shock absorber layout which makes vehicle more stable is of necessity.
