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.
