| 摘 要： | 为了在低储能条件下研究电磁发射过程中的刨削现象,要对电枢进行优化设计,使其在小口径发射试验装置中实现高初速发射。通过计算、仿真,对电枢尺寸、初始预紧力等参数进行优化,并进行预紧力、塑性性能和接触面积等相关参数的测试和实验,最终确定电枢型号,在保持良好电接触的条件下实现了高初速发射。

| Abstract: | Gouging will occur in the rails when the armature is moving at a high velocity in electromagnetic launch. The optimization of armature is designed in order to achieve high muzzle velocity without transition in the small caliber electromagnetic launching while researching the gouging with low energy. Optimization of the preload, size, plastic property, and contact area of the armature is presented in this paper. Some tests about these parameters have already been done. The model of the armature is thus determined, and high muzzle velocity is obtained with good electrical contact condition in launching. |
