| 摘 要： | 为了研究活塞式磁通压缩发电机（P-MFCG）电枢内部涡流及周围的磁场分布，在Maxwell方程组的基础上，对电枢附近区域的磁场模型进行理论推导，得出电枢附近区域涡流场的控制方程。采用Ansoft有限元分析软件对应用于P-MFCG的柱状电枢上感应涡流、磁感应强度以及电枢所受电磁力的分布进行仿真分析，其结果对电枢的优化设计有重要参考意义。

| Abstract: | In order to investigate the distribution of eddy current and magnetic field around the surface of the armature, the theory model containing the magnetic model of armature sliding region and the eddy field control equation of armature are derived based on the Maxwell equations. The distribution of eddy current and magnetic induction intensity on the cylinder armature of P-MFCG is simulated by Ansoft finite element analysis software, providing theoretic foundation for the optimum design of the armature. The simulation of magnetic force acting on armature provides us with a reference criterion for armature optimal design of P-MFCG. |
