| 摘要: |
| 采用有限元法研究了高速磁悬浮列车的悬浮和推进电磁场，重点研究了车辆在不同运行条件下悬浮力和推力的变化规律，并得出了经验公式。分析和计算结果表明，悬浮力和推力的大小与功角有关，并且由于定子齿槽和材料不连续的影响，悬浮力和推力都存在六倍频的波动。 |

| Abstract: |
| The levitating and propulsive electromagnetic fields of the high speed magnetic levitation vehicle is studied by using the finite element method. The tide of the thrust and levitation force varying along under the running condition is highlighted and an experiential formula is derived. According to the analysis and the calculation, the thrust and levitation force are related to the power angle, and the sixfold frequency undulation is found in thrust and levitation force due to the influence of the discontinuousness of the stator grooves and the material. |
