摘要为了解决某高初速传统杀伤榴弹发射器的减后坐力问题，提出一种将浮动发射原理运用到高初速自动榴弹发射器减后坐的设计方案。本课题主要工作是基于内弹道学理论与机械设计理论对35mm杀伤榴弹发射器浮动减后坐装置的首发启动装置和防瞎火装置进行设计。首先设计了整个首发启动装置和防瞎火装置的总体方案；然后设计了首发启动装置中的最重要的几个核心部件：后拉安装座、活塞、回转弹膛、机针，以及防瞎火装置中的棘爪、棘爪簧、凸轮、滑动拉杆、旋转式储能机构；并依据给定任务条件（弹丸初速，弹丸自重，枪管重量）进行内弹道学分析得出的后坐距离，从而确定后拉安装座与前端盖的基本尺寸，并确定了后拉过程提供能源的无战斗部弹药的装药量；最后利用计算机辅助设计软件SolidWork与AutoCAD对机构进行三维模型与二维图的绘制工作，其中包括各个三维装配模型，二维装配图，二维零件图。69377

Title The starting device design and misfire prevention
device design of automatic weapons floating launch
Abstract
In order to solve the traditional killing of a high muzzle velocity grenade launcher after reducing recoil problem, a floating emission principle applied to high muzzle velocity automatic grenade launcher sitting subtracted design. The main issue is based on first startup device after internal ballistics theory and mechanical design theory 35mm grenades launchers floating recoil reduction and anti-fire devices blind design. First designed for the entire first start means the overall program and blind anti-fire devices; then designed the first start of the most important means of several core components: Houla An installed base, piston, rotating the chamber, the needle, as well as anti-Dud means pawl, detent spring, cam, slide lever, a rotary energy storage mechanism; and according to the given task condition (muzzle velocity, bullet weight, barrel weight) were within ballistics analysis derived from the sitting, which OK Houla an installed base and the basic dimensions of the front cover, and identified after the drawing process to provide energy without warhead ammunition loading dose; and finally the use of computer-aided design software and AutoCAD SolidWork institutional draw three-dimensional model and two-dimensional graph work, including the respective 3D assembly model, the two-dimensional assembly drawing, 2D parts diagram.
Keywords： 35 mm killer grenade launchers; Floating launch; The recoil; Starting starter; Misfire prevention device
