SolidWorks40mm的3连发自动炮炮身设计

摘要提高火炮的射速和首发命中率对战车来说具有重要意义。本课题设计新型 40mm3 连发自动战车炮的炮身设计,在分析新型 40mm3 连发自动战车炮工作原理的基础上，设计适应新型 40mm3 连发自动战车炮的身管炮尾以及之间的连接部件等。此种新型三连发火炮采用横动式炮闩，装填埋头弹，通过大胆创新试图解决火炮中的一些问题。此设计中炮闩采用一次装填三发炮弹的结构，射击时通过炮闩的运动来实现三次射击。这对炮管，炮尾等部件的结构都有特殊的要求。具体设计时采用对已知参数的分析，计算出炮身个部件所需承受的压强大小并进行校核，对已知的材料等进行选择，设计结构。完成课题要求。69453

Title 40mm triple shooting artillery

Abstract

It is great significance to improve the rate of fire and starting shooting . This new Design is about a new 40mm artillery which can complete triple shooting. Based on the analysis of new 40mm artillery working,design the new 40mm artillery barrel,the connecting member and so on. The new triple shooting artillery use a new breechblock which can traverse,filling Cased Telescoped Ammunition,trying to solve some problems by bold innovation.This design have a special breechblock which can load three bullet after only one move,by breechblock＇s movement to achieve triple shooting.This structure have the special require for barrel and breech . Analysing the known parameter to calculate barrel＇s pressure when you design, then check strength,choose material which haven known. Finally,complete the task requirements.

Keywords Triple shooting Cased Telescoped Ammunition Barrel Breech Check strength
