城轨列车在曲线上的碰撞仿真分析

Simulation Analysis of Metro Train Collision on Curve Line

根据EN 15227:2020《轨道交通轨道车辆耐撞性要求》,一般在直线线路上对城轨列车碰撞进行仿真分析,在曲线线路上开展的碰撞研究相对较少。城轨列车在曲线线路上运行时同样会发生碰撞,这就提出了在曲线线路上的碰撞分析需求。为此,研究城轨列车在曲线上运动的碰撞仿真建模方法,开展仿真分析,并对比分析曲线碰撞与直线碰撞结果,为列车在曲线上的碰撞分析提供参考。

According to EN 15227:2020 Railway application-Crashworthiness requirements for rail vehicles,the collision simulation analysis of metro trains is generally carried out on straight lines,while the collision research on curved lines is relatively few.metro trains will also collide when running on curved lines,which leads to put forward the need of collision analysis on curved lines.Therefore,this paper studies the modeling method and simulation analysis of collision of metro trains moving on curves,and compares and analyzes the results of curve collision and straight collision,which provides reference for collision analysis of trains on curves.
