自动装填技术是改善火炮速射性的有效途径之一。该技术可有效保证大口径火炮持续恒定的射速，有利于提高火炮射击密集度，并能大幅度降低炮手的劳动强度。开展火炮弹药自动装填技术的研究工作，对提高和发展我国火炮总体技术，推动我国火炮事业长足发展都具有非常重要和现实意义。
目前我国大部分的自行火炮、坦克等都是手工装填弹药，只用一小部分火炮系统应用了半自动供推弹机构（即推弹机）。已知应用较为广泛的推弹机主要有液体气压式推弹机和链式推弹机。例如100 高炮应用的是液体气压式的推弹机，155 自行火炮采用的是链式推弹机。而这两者推弹机都有自身的缺点，液体气压式的推弹机重量太大，链式推弹机的推弹速度不能太快。气动弹射推弹机就能很好克服这些缺点，气动弹射推弹机的重量要比液体气压式的轻得多，而且气动弹射推弹机的推弹速度要比链式的快。
摘要本论文以气动弹射推弹机的推弹能力为研究目标，对如何模拟新型结构的气动弹射推弹机的推弹过程开展探索性的研究。首先，根据自行火炮武器系统的特点要求，分析、讨论并设计一种任意角自动推弹的推弹机总体方案。其次，根据气动弹射推弹机的总体方案，对该推弹机进行结构设计。再次，建立气动弹射推弹机的动力学模型，编写 MATLAB计算程序，对气动弹射推弹机的推弹过程进行动力学仿真，分析相应的仿真计算结果。最后，对新型的气动弹射推弹机的关键零件进行设计和校核。19342

Title Design and analysis of a pneumatic catapult shells push machine of the artillery
Abstract
The object of the study is new pneumatic catapult system, which can be used to pushing shells .The main work is the new the pneumatic push machine’s transmission simulation, get the new pneumatic catapult system’s pushing property for the next design. The technology of auto-loading is one of the effective ways to improve artillery shooting speed. The technology can be effective to ensure that large-caliber artillery continued firing rate and will be beneficial to the intensity of artillery fire, and can significantly reduce the gunner’s labor intensity. Carry out the research of the self-propelled artillery auto-loading technology is very beneficial for the improving of China's l self-propelled artillery technical and the rapid development of China's artillery.
By now, the most of our country’s self-propelled artilleries and tanks are hand-loading. More widely known applications is liquid-pneumatic push machine and chain push machine, the weight of the liquid-pneumatic push machine is too heavy, and the chain push machine transmission velocity is slow. But, the pneumatic push machine can conquer those problem.
The research objectives is new pneumatic push machine’s tansmission ability, to carry out exploratory research on how to simulate the new structure of the pneumatic push machine。First, according to the characteristics' requirements of self-propelled artillery, analyze and design a pneumatic push machine overall program which can transmiss bomb with arbitrary angle，Secondly, carry on structural design according to the pneumatic push machine overall program。Thirdly, establish a dynamic model of the pneumatic push machine and program MATLAB calculation procedure，carry on the dynamic simulation of pneumatic rammer and analyze the simulation results. Finally, designing and checking the key part of the new pneumatic catapult shells push machine .
