【摘要】 由于轨道表面与车轮踏面直接接触,其不平顺性质对高速列车的安全运行影响很大。本文基于多体动力学仿真软件建立了列车模型,实现了列车与轨道的耦合,并选取速度和加速度这两个参数为研究对象,分析了轨道不平顺的波长和幅值这两个重要参数对高速列车运行的影响。更多还原

【Abstract】 Because the tracks’ surfaces contact with the wheel treads directly,the characters of the track surface irregularity have a great influence on the safe running of high-speed train.On the basis of multi-body dynamic simulation software,a train model is built in this paper.The coupling of train and track is realized.Choosing the velocity and the acceleration these two parameters as the objects of study,the influence of the irregularity’s wavelength and amplitude these two important characters on the dynamic performance of high-speed train is analyzed.更多还原
