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 suspended electromagnet in the normally-guided high-speed maglev train simultaneously undertakes the tasks of levitation, propulsion and power generation, and its geometric parameters directly affect the performance of the train electromagnetic system. When optimizing the design of suspension electromagnet, we need to consider the performance of two subsystems, linear synchronous motor and linear generator. To this end, a globalized objective function is introduced to control the overall performance of the system. Based on the finite element analysis and calculation, the geometrical parameters of the suspension electromagnet are automatically adjusted by programmatic optimization design method. After many iterations, Optimize the design result.
