Abstract:In order to predict the wear of wheel tread of high-speed train under the situation of wheel/rail vibration behavior, a multi-body dynamic model of vehicle and a finite element model of wheel/rail rolling contact are established. The nonlinearities of suspension system of vehicle, contact geometric and creep force of wheel/rail are considered in those models. The variation of longitudinal and transverse creep force between wheel and rail are analyzed by using numerical simulation and the wear of wheel tread is predicted by the evaluation method of wheel/rail wear based on the wear work. The results show that: wheel/rail contact positions and longitudinal creep force changing with time under the situation of vibration behavior of the wheel/rail. The larger lateral displacement of wheelset and the normal force wheel/rail are, the greater longitudinal and lateral creep forces in wheel/rail contact patch are. And wear of wheel tread is most serious in this condition resulting in out-of roundness of wheel. The periodic wear of wheel tread is affected by the coupling of periodic change of the wheelset lateral displacement and the wheel/rail force. This is the root cause of complex multistage wear of wheel tread.
