Adams转管机枪可靠性研究
摘要转管武器为实现高速射击循环，各零件工作环境恶劣，机构间碰撞磨损现象严重，常由于零部件工作不可靠出现停射、炸膛等故障，严重时可导致人员伤亡和较大程度经济损失，可靠性问题十分突出，因此对其进行可靠性研究对于提升系统整体性能以及减少潜在损失都具有十分重要的意义。本文在某转管机枪结构及其工作原理的基础上建立了转管机枪可靠性模型，采用FMECA和FTA结合法分析了转管机枪的故障模式，并进一步对其可靠性指标进行分配，提供了可靠性分配的基本过程。并应用Adams软件对其可靠性薄弱环节——供输弹机构进行动力学仿真，验证并提高了其可靠性。本文介绍了可靠性设计的一般过程，为可靠性工程在武器系统中的应用提供了一定参考。47989

Title The reliability research of Gatling gun
Abstract
In order to realize high speed firing cycle, the operating conditions of each part of Gatling gun are extremely terrible and the collision and wear between mechanisms are very serious. The performances of each part are unreliable, which often lead to fire stop and bore premature. More seriously, that could also cause casualties and large economic loss. It is indicated that the reliability problem of Gatling gun is very prominent, therefore, studying the reliability of Gatling gun has a great significance in improving overall system performance and reducing the potential loss. The paper establishes the reliability model on the basis of the structure and working principle of Gatling gun, analyzes its failure model in method of FMECA and FTA, allocates its reliability index further which provides the basic process of reliability allocation and carries on a dynamics simulation into the reliability weak spot——ammunition feeding mechanism in use of Adams software which could verify and improve its reliability. The paper introduces the general process of reliability design that provides a certain reference on the reliability engineering application in weapon system.
