摘要：
Based on the kinetic theory of vehicle-turnout coupling system and the study of a domestic EMU and No.18 turnout used for passenger dedicated line, the vehicle-turnout coupling dynamics model was established using the multi-body dynamics software UM, to analyze the wheel-turnout action and the dynamic performance of the train passing through the turnout under the wheel wear state of the high-speed train. The model considered nonlinear factors such as vehicle suspension force element nonlinearity and wheel-rail contact geometry nonlinearity. A more practical non-elliptic multi-point wheel-rail contact algorithm was used to study the influence of profile wear on the dynamic performance of high-speed train passing through the turnout section under different operating mileage. The results show that the profile wear will increase the wheel rail vertical force, and decrease the lateral force. The profile wear has greater influence on the vertical vibration of car body, bogie frame and wheelset than on the lateral vibration. It has little impact on the derailment coefficient, but has a greater influence on wheel load reduction rate and wear power. It has greater influence on the lateral vibration of the turnout rail than on the vertical vibration. © 2020, Department of Journal of the China Railway Society. All right reserved.
