| The feasibility of reconnection electromagnetic gun was studied in this paper, using the reconnection electromagnetic launch technology theory. The impact factors of the gun launch performance were analyzed. A suggestion about the changing of the electromagnetic gun muzzle velocity was proposed.The classification and the basic working principle of electromagnetic launcher was outlined in this paper. The magnetic lines reconnection electromagnetic launcher was selected as research program, a mathematical model based on the acceleration mechanism of reconnection electromagnetic launch technology was established. The electromagnetic field domain of the reconnection electromagnetic gun was analyzed by means of using the Ansoft software, obtaining the electromagnetic field distribution and inductance distribution law of the driving coil. The reconnection electromagnetic gun was modeled and dynamic simulation was studied using the Ansoft Maxwell software. The motion characteristics of the system was analyzed, revealing the effects of the launch properties on the projectile initial position and initial velocity, projectile diameter, the structural parameters of the driving coil and driving circuit parameters. Based on this study, a program of variable muzzle velocity by changing the capacitor charging voltage was proposed, which capacitor is in the last one (the coil that closest to and less than the speed requirements) driver circuit. Some reference for the follow-up study of electromagnetic launch technology on the changing of the electromagnetic gun muzzle velocity was provided in this paper. |
