磁浮列车车辆轨道耦合振动及悬挂参数研究

A Study on the Vehicle Guideway Coupling Vibration and Suspension Parameters of Maglev Train

基于磁浮列车车辆轨道耦合振动模型，建立了动力学方程，利用编制的仿真程序对车辆轨道的耦合振动进行仿真分析，对于悬挂参数特别是模块侧滚约束参数的影响进行定量研究，确定了悬挂参数的取值范围，并据此对青城山磁浮试验车的悬挂参数设计提出了建议。

Based on a vehicle guideway coupling vibration model of maglev train, the equations of motion are obtained. A simulation program is designed to simulate the vehcile guideway coupling vibration. The effects of suspension parameters, especially the restraint parameters of module roll, on the dynamic response are analyzed. The limit values of suspension parameters are determined, according to which, suggestions are given to the design of the testing maglev vehicle of Qingchengshan.
