Abstract

Wheel-set hunting is an important and random lateral movement when wheel-set running on the track. Firstly a vehicle-bridge dynamic interaction model is established, in which the lateral wheel-rail interaction is defined by Kalker linear creep theory with the calculation of detailed wheel-rail contact adhesion geometric parameters and creep force. Then with the case of a high speed train passing a 32 m simply-supported beam bridge, the wheel-set hunting movement is calculated according to the relative vehicle and bridge lateral movement. And the characteristics of wheel-set hunting with different train speed and bridge stiffness are discussed. Then a simple lateral wheel-rail interaction is defined with close contact and no elastic deformation, and the contribution of hunting movement to coupling vibration of vehicle-bridge system is summarized in this method. The results show that the wheel-set hunting movement could be neglected when analyzing the bridge response, but it should be considered when analyzing the vehicle response in the vehicle-bridge interaction.
