摘要小半径曲线上中低速磁浮车辆-轨道系统的动力响应对车辆安全运营具有重要意义，但当前研究极少涉及。运用有限元和多体动力学方法，建立了中低速磁浮车辆-小半径曲线段高架轨道耦合动力学模型，考虑空间动态磁轨作用以及轨道关键部件的参振作用，分析了小半径曲线上的车辆-轨道系统动力响应。结果表明：二维磁轨关系会过大的估算曲线段磁轨作用力；曲线段磁浮车辆车体主要为2Hz以下的低频晃动；曲线段连续梁钢构高架轨道的振动主要由0~20Hz的轨道整体弯扭变形和80~100Hz的F轨局部弯扭变形引起；轨道垂向振动加速度缓和曲线段大于圆曲线段，横向振动加速度圆曲线段大于缓和曲线段，缓和曲线段振动加速度对车速变化更为敏感。研究结果可为曲线段磁浮高架轨道设计和车辆安全运营提供理论依据。

Abstract：The dynamic response of low-medium speed maglev vehicle-track on tight curve is of great significance to the safe operation of vehicles, but it is rarely involved in the current research. Using finite element and multi-body dynamics methods, the dynamic model of the elevated track with low-medium speed maglev vehicle and tight curve was established. The dynamic response of the vehicle-track system on the tight curve was analyzed by considering the dynamic magnetic track action in space and the interaction of key components of the track. The results show that The 2-D magnetic track relationship will be too large to estimate the magnetic track force in the curve segment; The body of maglev vehicle in the curve section is mainly low-frequency sloshing below 2Hz. The vibration of the elevated rail with continuous beam in curved section is mainly caused by the overall bending and torsional deformation of the track at 0-20Hz and the local bending and torsional deformation of F rail at 80-100Hz. The vertical vibration acceleration in the easing curve segment is greater than that in the circular curve segment, and the transverse vibration acceleration in the circular curve segment is greater than that in the easing curve segment. The vibration acceleration in the easing curve segment is more sensitive to the change of vehicle speed. The research results can provide a theoretical basis for the design of maglev elevated track in curve section and the safe operation of vehicles.

Key words： low-medium speed maglev transport flexible track beam dynamic magnet-track relationship vehicle-guideway coupling vibration dynamic curve negotiation
