| Abstract: | A mechanical model to analyze the dynamic performance of train and transition section between roadbed and railway bridge was established and a series of reasonable criterions were put forward too.Based on this,the initial deformation of rails due to different subsidence of roadbed and bridge abutment,the effects of the direction and speed of train on the dynamic performance of wheel/track system were studied.At last,the method to determinate the length of transition section was suggested. |
