高速万向轴式动力车转向架的参数研究

Study on Parameters of Cardan Shaft Type of High Speed Power Car Bogies

分析了一系定位刚度对蛇行临界速度、二系悬挂刚度对平稳性能的影响，以及各类减振器阻尼对动力学性能的影响。总结出了高速动力车转向架的参数选择原则和各主要参数的优化范围。

The effects of suspension stiffness and damping are investigated on the basis of the parameters of the preliminary design for a cardan shaft type of high speed power car bogies. The design principles and the optimal range of main parameters are suggested. The correctness of the selected parameters is examined with a nonlinear resolution method.
