分析了航空器设计/制造单位在故障、缺陷原因分析方面存在的问题,研究建立了航空器设计/制造单位故障、缺陷原因分析模型,包括原因分析、原因要素列表、统计分析等内容。其中,重点对比分析了常用原因分析模型的优点和不足,包括Reason模型、SHEL模型、人-机-环管-模型、鱼骨图模型;分析了航空器设计/制造单位故障、缺陷原因分析的特点,建立了故障、缺陷原因要素列表;最后,案例分析表明该模型具有实用性。
The problems in the design and manufacture of aircraft were analyzed in the aspects of failure and defect analysis. The model of failure and defect analysis in aircraft design and manufacturing unit was established, including the analysis of causes, the list of the causes and the statistical analysis. Among them, the advantages and disadvantages of common cause analysis models are analyzed and compared, including Reason model, SHEL model, man-machine-loop model and fishbone graph model. The characteristics of aircraft design / manufacturing unit failure and defect reason analysis are analyzed , Established a list of causes of failure, defects; Finally, case analysis shows that the model is practical.
