摘　　要：为了改善六极轨道电磁发射器电枢和轨道的部分位置电流密度过大且分布集中现象,文中基于Ansoft软件对其进行有限元分析,分析验证了推进力产生原理及中心磁场屏蔽原理,同时也得到电流密度过大且分布集中的现象较为严重。将电枢结构进行优化,对电枢优化后的发射器模型进行仿真,结果显示优化后的电枢和轨道最大电流密度降低,分布更加均匀合理,而且电枢推进力较之前也有较大提升。说明改进电枢能很好改善电流密度过大且集中的现象。In order to improve the current density of six part of polar orbit electromagnetic launcher rail and armature is too large and con- centrated phenomenon. In this paper, the finite element analysis software of Ansoft which is based on analysis, verify the propulsive princi- ple and central magnetic field shielding principle, and also the current density is too large and concentrated phenomenon is more serious. The armature structure optimization, the simulation model of the transmitter armature after optimization, results show that the optimized rail and armature current density decreased and the distribution is more uniform and reasonable, and the armature propulsive force is also great- ly improved than before. It shows that the improved armature can improve the current density and concentration.
