高速磁浮列车-桥梁耦合振动响应分析与评估

Analysis and evaluation of high-speed maglev train-bridge coupling vibration responses

为了对速度600 km/h的三节车厢下高速磁浮列车-桥梁耦合动力响应进行评估,将磁浮列车等效为弹簧-质量系统,采用ANSYS中的APDL自编程序,进行600 km/h三节车厢下高速磁浮列车-桥梁耦合振动响应的分析与评估。结果表明:三节车厢下高速磁浮列车-桥梁耦合的动力响应值在规范要求内。

In order to evaluate the dynamic response of high-speed maglev train-bridge coupling under three carriages at a speed of 600 km/h,the maglev train is taken as equivalent to a spring-mass system,and then APDL self-programmed in ANSYS is used to analyze and evaluate the vibration response of high-speed maglev train-bridge coupling under three carriages at a speed of 600km/h.The results show that the response values of the high-speed maglev train-bridge coupling under three carriages are within the specification requirements.
