为了深入研究并提高新型四极轨道电磁发射器增强型结构模型的性能,利用AnsysMaxwell仿真软件,以运用正交试验法为基础,通过Fillet处理和设置不同枢轨接触面等方法,不断对该模型电枢与轨道结构进行优化设计。结果表明,当该四极轨道电磁发射器采用结构优化后的C形电枢以及凸面轨道时,模型整体性能得到较大改善,与其基本型相比,电枢与轨道电流分布更加均匀,电流过度集中现象基本消除,电磁推力增大7.2%,电流密度最大值减小44.2%。

The research shows that the structure new quadrupole track electromagnetic launcher augmented structure of has better performance in electromagnetic thrust and current distribution. In order to further study and improve the performance of the model, a series of optimum design of armature and rail structure were carried out by means of orthogonal test method, Fillet processing and setting different contact surfaces of armature and rail, which were based on the Ansys Maxwell simulation software.The results show that when the quadrupole track electromagnetic launcher adopts C-shaped armature and convex track with optimized structure, the overall performance of the model is greatly improved. Compared with the basic type, the current distribution of armature and rail are more uniform, the phenomenon of excessive current concentration is basically eliminated, the electromagnetic thrust increases by 7.2%, and the maximum current density decreases by 44.2%.
