Dynamic Response of Flexible Wheelset High-speed Train Passing Through Turnouts
To research the dynamic response of high-speed trains passing through turnouts under the condi-tion of flexible wheelsets,a rigid-flexible coupling dynamic simulation method was adopted.Based on the CRH380 high-speed train model,a vehicle-switch and rigid-flexible coupling dynamic model was estab-lished under the condition of flexible wheelsets.Taking the flexible wheelset high-speed train model as the research object,through switch 18,the safety of vehicle models under the condition of wheelset flexibility and full rigid structure,wheel-rail dynamic interaction,vehicle vibration acceleration and wheel-rail con-tact position distribution index of the vehicle model were analyzed.The simulation results show that the flexible wheelset high-speed train model is a significant impact on the wheel rail dynamic interaction of the vehicle,and is a relatively small impact on dynamic indicators such as safety,vehicle vibration accelera-tion,and wheel rail contact position distribution.
