Analysis of Armature Material in Synchronous Inductive Electromagnetic Propulsion

Some theoretical analysis of the synchronous inductive electromagnetic propulsion was carried out and the equivalent circuit model of single-stage system was established,thus setting up a relation with the eddy current and the armature material parameters.Based on the electromagnetic field finite element software,the influence of armature material parameters on armature stress,armature speed and energy operating fator was analyzed.Simulation results reveal that the armature material parameters influence the armature stress,the operating factor and the mass of the projectile directly and the aluminous is the best choice for making armature.This result is useful for the design of armature.
