摘　　要：本文推导了轨道与快速磁浮列车悬浮电磁铁的一般耦合电磁力公式,并利用三维电磁有限元仿真对解析公式进行验证。解析分析表明,在同样悬浮载重下,减小轨道极面或电磁铁极板宽度,增大悬浮间隙,可有效提升电磁铁的被动导向能力。另外,本文建立了基于主动悬浮控制的两节车编组的快速磁浮列车动力学模型,并考虑实测轨道不平顺激励,研究了不同轨道与电磁铁极板宽度匹配下,磁浮整车在较高速度区间的横向动态响应。仿真结果显示,适当减小轨道极面宽度,可有效提升车辆被动导向性能,减小电磁铁横向偏移量和降低轨道发生碰撞的风险,提高车辆较高速度下的运行平稳性。This paper derives the general coupling electromagnetic force formula between the rail and the levitation electromagnet of a fast maglev train,and verifies the analytical formula using three dimensional electromagnetic finite element simulation.Analytical analysis demonstrates that under the same suspension load,reducing the rail pole face or electromagnet pole plate width while increasing the levitation gap can effectively enhance the passive guidance capability of the electromagnet system.Furthermore,this paper establishes a dynamic model of a fast maglev train with a two-car formation based on active levitation control.Incorporating measured track irregularity excitation,the study inves-tigates the lateral dynamic response of the maglev vehicle within the high-speed range under different matching relationships between rail and electromagnet pole plate widths.Simulation results indicate that properly reducing the rail pole face width can effectively enhance the passive guidance performance of the vehicle,reduce electromagnet lateral displacement,lower the risk of rail contact,and improve the running stability of the vehicle at elevated speeds.
