摘　　要：针对弹药自动化生产过程中合膛检测设备可靠运行问题,提出了基于FMEA(Failure mode and effects analysis,失效模式影响分析)与FTA(Fault Tree Analysis,故障树分析)的合膛检测设备可靠性分析方法。分析了合膛检测设备的组成及运行过程,完成了合膛检测设备故障模式及失效成因分析,并采用措施优先级(AP)方法构建了自动合膛检测设备的FMEA表,确定了关键可能的潜在失效模式以及后果,完成了基于FTA的自动合膛检测设备的故障树分析。通过建立磨损模型,计算了不同装配检测次数下的自动合膛检测设备的可靠度。所提方法可以为弹药自动生产装配过程中合膛设备的可靠运行及维护等提供依据,提升了自动合膛检测设备的稳定性。Aimed at the problem of reliable operation of the chamber gage inspection equipment in the automatic production process of ammunition,it was proposed that a reliability analysis method of the chamber gage inspection equipment based on FMEA(Failure Mode and Effects Analysis) and FTA(Fault Tree Analysis).The composition and operation process of the chamber gage inspection equipment were analyzed,and the failure mode and failure cause of the chamber gage inspection equipment were analyzed,The FMEA table of the automatic chamber gage inspection equipment was constructed by using the AP method,the key potential failure modes and consequences were determined,and the fault tree analysis of automatic chamber gage inspection equipment based on FTA was completed.Based on the establishment of wear model,the reliability of automatic chamber gage inspection equipment under different assembly inspection times was calculated.The method proposed could provide a basis for the reliable operation and maintenance of the chamber gage inspection in the automatic production and assembly of ammunition,and improve the stability of the automatic chamber gage inspection equipment.
