一种面向飞机制造和维护的质量风险识别与评估方法

各飞机制造厂一直在努力减少飞机制造与使用维护过程中的质量安全事件。单纯使用生产制造阶段的过程故障模式影响分析（PFMEA）方法进行质量风险识别与评估时，存在分析不包含飞机使用维护过程、失效模式识别率和准确性不高、建议措施不完善等问题。提出质量风险识别与评估方法，将制造过程PFMEA 范围拓展到使用、维护过程，并以设计故障模式影响分析（DFMEA）作为PFMEA 的输入，以扩大分析范围，改善失效模式的识别率和准确性；使用树形分析图方法对风险控制措施进行覆盖性和重复性分析，获得完整、最简措施集。使用该方法对某液压系统一根液压泵循环散热导管进行分析，结果表明：本文提出的方法可以更全面、更准确地分析飞机制造与使用维护过程中的质量风险，获得更为优化的质量风险控制措施集合。

A Quality Risk Identification and Assessment Method for Aircraft Manufacturing and Maintenance

A quality risk identification and assessment method for aircraft manufacturing and maintenance based on FMEA is applied to analyze the potential failure modes and their causes of aircraft in manufacturing and maintenance, evaluate these failure modes, and formulate recommended measures for important failure modes to reduce or avoid the occurrence of failures. This paper presents a set of mapping rules for the application of DFMEA analysis results in risk identification and assessment of manufacturing and maintenance quality. The analysis scope is extended from the design end to the use and maintenance of aircraft. Through the combination of the above methods and measures, the technology realizes the analysis and evaluation of the potential failure mode, failure cause, Severity, recommended measure effect, measure coverage and repeatability in the manufacturing and maintenance process starting from the design stage, which can more scientifically and comprehensively analyze, evaluate and deal with the quality risk of aircraft manufacturing and maintenance.
