摘要： 依据地铁列车结构及地铁列车的运用条件,建立地铁列车碰撞有限元模型。论文通过非线性有限元软件LS-DYNA,从列车端部结构变形、列车各部位吸能情况、列车加速度和转向架车轮的位移响应等方面分析了列车与刚性障碍物在大角度下（25 °）的斜向碰撞动力响应。

Abstract: According to the structure and operation conditions of metro train, the finite element model of metro train collision is established. Through the nonlinear finite element software LS-DYNA, the oblique impact dynamic response between the train and the rigid obstacle under a large angle (25 °) is analyzed from the aspects of the structural deformation of the end of the train, the energy absorption of each part of the train, the acceleration of the train and the displacement response of the bogie wheel.

Key words: Metro train, Rigid obstacle, Oblique collision, Dynamic response
