Title Analysis and design of a police submachine gun
Abstract
Police submachine gun is a repeating firearms holding with two hands, firing Pistol Ammo. Its tactical role between the pistol and rifle, with firepower, power moderate, short form features.It can make a warhead stay on target in the body, indeed the knockdown of target, and can prevent the ricochet or excessive through to prevent harm the hostages or friendly .It’s suitable for special combat environment very much. So the police submachine gun plays an important role in the war against terrorism. The modular weapon is the big direction of the world automatic weapon development, have great development potential and advantage. Will be modular applications in police submachine gun design can realize police weapons, multi-function, multi use and adapt to a variety of special operation conditions. This paper has completed the design and calculation of internal ballistics, the mass of the bolt and barrel recoil spring etc. According to the results of design calculation, the 2D drawings and assembly drawings of parts are drawn, and the 3D model is created.

冲锋枪是枪械中比较年轻的枪种，其英文名称是Sub-machinegun，本意为“小机枪”，所以许多国家也称之为“短机关枪”、“机关卡宾枪”、“手枪式机枪”，我国早期称它为“手提机枪”。它是单兵使用的自动武器，主要装备步兵、空降兵、侦察兵、炮兵、摩托部队、警卫部队和其它军兵种，以其猛烈的火力杀伤近距离的有生目标[1]。
