摘要
参考国内外有关地铁、轻轨车辆耐碰撞设计规范及准则,结合某型地铁列车,依据地铁列车头车车体结构以及地铁列车的运用条件,利用显式有限元软件ANSYS/LSDYNA,建立地铁列车头车碰撞的有限元模型,对碰撞过程进行数值模拟。研究结果表明,该型地铁列车头车的耐碰撞性能满足相关标准的要求。
In this paper, the design specifications and guide- lines of crashworthiness for metro train and light rail vehi- cle both in China and abroad are introduced. Combined with a special type of metro train, a collision finite element model of metro train head car is established by using explic- it finite element software ANSYS/LSDYNA,and a numeri- cal simulation of crash process is carried out. The result shows that the crashworthiness of this metro train head car is consistent with requirements.
