高速动力车的平稳性分析

Riding Quality Analysis of the High Speed Power Car

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住和轮轨动作用力水平作出了评价。

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.
