Armature Optimization Design Based on Orthogonal Test

Armature is the core component of electromagnetic launcher. It not only plays the role of constituting current loop, but also provides launching power for projectile. Therefore, armature optimization is a key step to improve the comprehensive performance of six-pole orbital electromagnetic launcher. In this paper, the finite element simulation software Ansoft Maxwell is used to simulate and analyze the armature, and the influence of the main size of armature on the maximum current density and electromagnetic thrust of armature are obtained. At the same time, the optimal design of armature size is carried out by using matrix analysis method in orthogonal experiment. Finally, the optimized armature is verified by simulation. The results show that the optimized armature has the smallest maximum current density and the largest electromagnetic thrust in all size combinations. (paper)
