Title The design and analysis of light-weight carbine with large capacity
Abstract
Compared to the rifle, carbine has the advantages of short length and light-weight, convenience of carriage and operation. Therefore, carbine has been paid much attention all over the world by armies, especially by the special operation forces (SOF). Recently, with the sudden change of war forms and the ever increasingly gravity of anti-terrorism, the more high requirements of the carbines are proposed by SOF: greater power, better firepower sustainability, convenient operation. By studying the light-weight carbine with large capacity, the design requirement of light-weight and large capacity is expected to achieved so as to provide the technical basis for the development of new carbines. Compared to the conventional weapons, The light-weight carbine with large capacity to be designed has lighter weight, more compact structure, can fire 30-rd magazine or 100-rd drum. Therefore, it has larger capacity and longer firepower sustainability. The overall scheme design of the designed carbine was conducted and the structure designs of its main mechanisms and parts were completed. The 3-D modeling and part 2-D engineerings of the designs were carried out. And the necessary analyses and calculations were also conducted.

卡宾枪，即马枪、骑枪。它是枪管比普通步枪短，子弹初速略低，射程略近的较轻便步枪。卡宾枪的名称来源于英文“Carbine”的译音，卡宾枪实际上归类属于步枪，可以说它是步枪的“忠实伴侣”。卡宾枪一般采用与标准步枪相同的机构，只是缩短了枪管，是一种枪管较短，质量较轻的步枪，有人给它下了个简单定义——短步枪。至于卡宾枪的枪管究竟有多短，一般认为不超过558.8毫米。据英国《大不列颠百科全书》记载，这种枪全长914毫米，质量不超过2.7千克[1]。
1．1 研究背景
卡宾枪与冲锋枪发射不同的弹药，两者既有共同特点，也有显著区别。卡宾枪与冲锋枪相同之处为：短而轻，机动性好。两者相比主要区别在于：冲锋枪火力密集，但由于发射手枪弹，威力较小，射程较近；卡宾枪属于步枪类，发射步枪弹，与使用手枪弹的冲锋枪不同，在威力和射程上优于冲锋枪[2]。
