A study on temperature field simulation of the driving coil of electromagnetism drive

摘要

Electromagnetism drive is launcher which utilizes magnetic traveling wave produced by impulse or alternating current to drive projectiles with coil or magnetic material, essentially is a linear electric motor. The heat wasting affect coil gun's efficiency and capability, high temperature of driving coil will reduce its life, indeed burnout coil, and when enhancing firing rate, we need calculate effect of temperature rising. This paper analyze electromagnetism drive's launch principle, have established single shoot wink state temperature field math model, have progressed simulation calculating by MATLAB software according as the model.
