摘要

针对部分型号CRH高速动车组在线路上运行时出现车体低频横向晃动而严重恶化旅客乘坐舒适度的问题，为了找出抑制车体低频横向晃动的有效措施，首先建立了车辆系统多刚体动力学模型，基于时域仿真分析获得了车体低频横向晃动的主要影响因素，最后采用根轨迹分析技术研究了其主要影响参数对车体低频横向晃动的影响规律。研究结果表明，选取适当的悬挂参数、轮轨参数以及车体质量参数可以避免车体低频横向晃动的产生。

Abstract

The low-frequency carbody cross swaying of some CRH high-speed trains were emerged in the process of line tests, whichcaused a significant deterioration for passengers ride comfort. In order to obtain the effective measures to suppress the carbody swaying, themultiple rigid body dynamic model of a high-speed vehicle was set up firstly. Then, based on the time domain dynamic simulations, the mainfactors influencing the low-frequency carbody swaying were obtained. At last, the root lotus analysis was used to investigate the effect ofcritical parameters on the low-frequency carbody swaying. It was shown that, proper selection of suspension parameters, wheel railparameters and carbody mass parameters could avoid the offensive low-frequency carbody swaying.
