| Abstract: | In this paper, based on a simplified train two-dimensional collision model, the differential equations were established.Furthermore, the equations were solved to investigate the dynamic behavior of the train after collision. The dynamic characteristics of the train under various conditions were obtained, including the maximum compression force of couple, the maximum closing translational velocity and the maximum closing angular velocity. Moreover, the sensitivity analysis was performed to discussthe influen... |
