摘要:
强烈的横风荷载会影响磁浮列车横向稳定性和安全。为全面了解横风荷载下电磁悬浮（EMS）型磁浮车辆的动态响应特性，建立了一个精细化的3D磁浮车辆多体动力学模型，并利用CFD（计算流体运动学）方法获得了磁浮车辆的气动载荷系数。基于“中国帽子风”阵风风速曲线计算生成横风荷载，进而通过时域动力学仿真，最终获得磁浮车辆车体与悬浮架的动态响应，并从车体位移、电磁悬浮系统和关键部件等方面细致全面地分析了横风荷载下EMS型磁浮车辆动态响应特性。
Abstracts:
Strong cross wind loads will affect the lateral stability and safety of maglev train. In order to fully understand the dynamic response characteristics of EMS maglev vehicle under cross wind loads, a refined 3D multi\|body dynamic model of maglev vehicle is established. The aerodynamic load coefficients of maglev vehicle are obtained by CFD method. Then the cross wind loads are calculated based on the gust wind speed curve of "Chinese hat gust". Finally, the dynamic response of the maglev vehicle body and suspension frame is obtained through the time domain dynamic simulation. The dynamic response characteristics of EMS maglev vehicle under cross wind loads are analyzed from the aspects of vehicle body displacement, electromagnetic suspension system and key components.
