摘　　要：常导高速磁浮列车长定子直线同步电机由于特殊的分离结构,气隙由悬浮与导向系统决定,导致牵引力与悬浮力容易受到悬浮与导向系统性能的影响。研究了一个长定子段下垂、悬浮磁极模块纵向倾斜和横向偏移三种工况对气隙的影响,基于有限元软件建立了2D与3D有限元模型,计算分析了长定子直线同步电机的牵引力和悬浮力,揭示了气隙变化对力的影响规律。分析结果可以为高速磁浮列车的牵引系统设计与控制提供参考。Due to special separated structure of long-stator linear synchronous motor in high-speed nomal conditioning maglev train,its air gap is decided by levitation and guidance systems which causes the traction force and levitation force easily influenced by performances of levitation and guidance system.The influence on air gap of three working conditions including position drop of one long stator section,longitudinal inclination of levitation magnet module and transverse position offset were inveetigated.Based on FEM,the 2D and 3D models were erected,and the traction force and levitation force were calculated and analyzed.The influence rule on forces of air gap variation was deduced.The analysis results could provide references to the design and control of the traction system in the high-speed maglev train.
