摘要
为计算电磁型磁悬浮列车(EMS-MAGLEV)使用的直线同步电机的牵引力及悬浮力,提出了用虚功法进行电磁力计算;同时建立了EMS型磁悬浮列车的有限元分析计算模型,推导出牵引力和悬浮力的计算公式,并将计算结果与成熟的商业软件ANSYS计算出的结果进行了比较,从而证明了用虚功法计算电磁力的正确性;另外,上述方法可以直接添加进现有的有限元软件,具有很好的兼容性。
The virtual work method is presented for the electromagnetic force computation of linear synchronous motor （LSM） used in the electromagnetic levitated vehicle in this paper. The formulation is then derived from this method. The model of EMS-MAGLEV is established and the propulsion and levitation forces are computed. Then the results, which are then compared to those from the commercial software ANSYS, prove the validation of this method. Another advantage of this method is that the computation is directly based on the conventional finite element method （FEM）, and it can be compatible with existing FEM electromagnetic packages.
