Dynamic research on 2-stage reluctance electromagnetic launcher

Abstract

During the process of electromagnetic launching, the electromagnetic force applied to the projectile correlate with the structure, trigger position and initial velocity. So, it’s very important to choose appropriate trigger position with different initial velocity in multi-stage reluctance launcher system. Two dimension finite element models of reluctance electromagnetic launcher are established based on the simulation environment of Ansoft Maxwell 2D. The effect of trigger position, initial velocity and their rational combination on multi-stage reluctance launcher are simulated and discussed. It can be seen from the results of simulation that different initial velocities have their optimum trigger positions in multi-stage reluctance launcher system. And then, their rational combination can improve their performance effectively.
