摘要
建立了列车与路桥过渡段动力特性分析模型 ,确定了一套轨道过渡段动力特性的评价指标 ,分析了由基础沉降差引起的钢轨初始变形以及行车方向、行车速度对轮轨系统动力性能的影响 。
A mechanical model to analyze the dynamic performance of train and transition section between roadbed and railway bridge was established and a series of reasonable criterions were put forward too.Based on this,the initial deformation of rails due to different subsidence of roadbed and bridge abutment,the effects of the direction and speed of train on the dynamic performance of wheel/track system were studied.At last,the method to determinate the length of transition section was suggested.
