摘要本文对埋头弹机枪的总体方案进行了探索和分析，首先通过对埋头弹结构原理的分析，开展了相对应的埋头弹结构设计。然后开始根据弹的特征开始选定机枪内部机构的运作方式，通过对于各机构特点分析，先后选定了该型机枪的自动方式、闭锁方式、供弹退壳机构、击发机构、发射机构和复进簧，并使用Solidworks软件建立三维模型。其次围绕着旋转式弹膛供弹的方式，进行了供弹机构的仿真分析。接着由仿真中获得的自动机数据和埋头弹数据完成对枪管进行长度、壁厚以及导气室参数的计算。最后完善机枪的外形并满足功能需求，添加了枪托、握把、皮卡汀尼导轨，并根据人机工程学对于整枪的外形进行调整，获得全枪总体布局方案。75520

Title The general design of small-caliber Cased Telescoped Ammunition machine gun syestem                       

Abstract The article shows the exploration and analysis on the overall plan of Cased Telescoped Ammunition machine gun。 First of all,  through the analysis on the principle and structure of CTA,the paper carried out the design of CTA。 Then according to the features of ammunition,the paper initiated the work on selecting the way of machine gun interior organization movement, through the analysis of the characteristics for the mechanism, the paper has selected the type of gun automatic method , blocking mechanism, ammunition feed mechanism,  percussion mechanism, shooting mechanism and counter-recoil spring, then using Solidworks software to establish three-dimensional model。 Second, around rotating chamber ammunition feed mechanism,The paper carried out the simulation and analysis for the ammunition feed mechanism。 Next by the automaton of data obtained from the simulation and CTA, the paper completed the calculation of barrel length, wall thickness and parameters of guide chamber。 Finally the paper improved the appearance of the gun and functional requirements, added a gunstocks, grip, Picatinny rail , and according to the man-machine engineering to adjust the appearance of the gun, then obtained the gun general layout scheme。
