Abstract According to the characteristic of wheel/rail interaction in the railway tracks，this paper establishes a simple lateral track model under lateral shock force. Based on a series of hypothesis, the program of wheel/rail dynamic interaction has been worked out depending on MATLAB Simulink?.. The dynamic effect of the rail fastener as well as the ballast lateral stiffness on the transverse vibration characteristics of wheel/rail system and rail wears on curved track are investigated as they have been varied. The results show that the Wheel/rail interaction would be improved and rail wears could be alleviated through selecting rational parameter of curved track.
