Simulating optimization on linear propulsion mortor for reluctance-type electromagnetic gun

Based on the basic structure and principles of reluctance type guns to perform linear propulsion motor design and optimization. Using Ansoft Maxwell software model, the initial mover position, control circuit, the mover materials, and the structure of the stator core shape were optimized, and resultantly the speed optimization obtained under different parameter. The influence of relationship between different parameters on the optimizing effect was explored. The results show that, the initial position, external control circuit and structure have better optimization results. Wherein the external circuit control optimization is the best because the efficiency of the guns has a revolutionary improvement and its control method is unique. Finally optimization design of both motor body and external circuit were given for physical manufacturing validation studies. The simulation results show that this design can achieve good acceleration with energy density of a crossbow.
