高速动力车的平稳性分析

在高速动力车的设计中为了获得良好的动力学性能，采用了许多与传统机车结构不同的新技术。本文根据高速动力车的结构，建立了合理的计算模型，用随机响应方法计算了高速动力车的平稳性指标和轮轨动作用力，介绍了平稳性和轮轨动作用力的评价标准，对高速动力车的运行平稳性和轮轨动作用水平作出了评价。

Riding Quality Analysis of the High Speed Power Car

In order to obtain good dynamic performance,many new techniques are adopted in the design of high speed power cars the construction of which are different from traditional locomotives. This paper establishes a rational calculation model according to the construction of high speed powet cars,calculates riding index and wheel-rail dynamic interaction with their estirnation criterion level of the high-speed power car.
