摘　　要：常导型高速磁悬浮列车中的悬浮电磁铁同时承担着悬浮、推进、发电等多项任务,其几何参数直接影响到列车电磁系统的性能。在对悬浮电磁铁进行优化设计时,需要综合考虑直线同步电机和直线发电机这2个子系统的性能。为此引入全局化的目标函数对系统的总体性能进行控制,并以有限元分析和计算作为基础,采用程序化优化设计方法对悬浮电磁铁的几何参数进行自动调整,经过多次迭代计算可得到优化设计的结果。The suspension magnet in high speed EMS-magtev system functions at the same time as suspension, propulsion and power generation, and its geometrical parameters have direct effects on the performances of the maglev system. During its optimization design, performances of the two sub-systems of linear synchronous motor and linear generator have to be taken into integral considerations. Therefore the fullscale target functions are introduced for control on the general systern performances. Based on FEA and calculations, programmed optimum design method is adopted for the automatic adj ustment of the geometricat parameters of the magnet. The results of optimum design are derived from iterative calculation.
