PAM-CRASH is used to simulate crashworthiness of railway passenger vehicle with large deformations. By using PAM-CRASH parallel function, a model with six million degree of freedom is developed to analyze the crashworthiness between two railway vehicles with another two railway vehicles. On the basis of the calculation results, the deformation law of the main absorbing energy structure of the vehicle body is analyzed. Draught beam and buffer beam are the main components of energy absorption; the results of head injury and leg injury show that train's crash and secondary crash are the mains reasons for passenger injury. Some shortcomings in design are found, and some corresponding measures for improvement are given. The crash simulation with large deformations of a type of railway passenger vehicle was studied in this paper by using PAM-CRASH software. From simulation data, two conclusions were obtained: (1) Draught beam and buffer beam are the main components of energy absorption, and it can increase the stiffness of the failure place to improve their energy absorption characteristic. (2) The injury of passengers not only has relation with the train crash, but also has relation with the secondary crash of passenger. So the design of vehicle body should be optimized to increase its crashworthiness, and some measures should be taken to avoid the secondary crash of passenger as far as possible.
