Title Simulate And Analyze The Main Component Of Nonfatal Anti-riot Electromagnetic Gun

Abstract

Electromagnetic launch is a device of launching payloads by using electromagnetic force, driving load by electromagnetic force acting. This technology, launching objects by using electromagnetic force instead of powder, can overcome the limitations of powder and rocket launchers, improve the speed of the objects leaving shell, increase the kinetic energy when it leaving shell, and reduce the cost of each launch. Furthermore, shooting without sound, no smoke and no muzzle flame, it has a good shot hidden. In today’s condition that the voice of nuclear arms control is growing, it ’ s more important and of significance to study the technology of electromagnetic launch.

In this paper, we summarize the prior art of electromagnetic gun and propose three different current types of emission methods combined with electromagnetic emission technology. According to their different emission characteristics and the characteristic of pistol, we choose reluctance coil electromagnetic emission for our research program. We analyze the electromagnetic field of model by an soft to get the element of affecting the dimension of the electromagnetic force. Optimizing the size of coil and pellet.

Specific contents are as follows:

a) We summarize the prior art of electromagnetic gun.

b) We analyze the electromagnetic field of model by an soft

c) Optimizing the size of coil and pellet.
