| 摘 要： | 立体物料仓库单元是钣金自动化智能生产线中重要的板料储存中心，其可靠性问题直接关系到钣金自动化智能生产线的可靠性，因此，对钣金自动化智能生产线的立体物料仓库单元机械系统进行故障模式及影响分析(FMEA)十分重要。针对传统FMEA中缺少功能和故障因果关系分析的问题，提出使用维护感知设计环境(MADe)软件对立体物料仓库单元的机械系统进行功能分析和故障数据分析，并建立立体物料仓库单元的功能模型图和机械系统的故障因果关系图。在此基础上，根据立体物料仓库单元功能模型图构建机械系统的模糊认知图(FCM)邻接矩阵，再通过计算得出立体物料仓库单元机械系统的FMEA表。对立体物料仓库单元机械系统进行基于MADe软件的FMEA分析显示，所提方法对提高钣金自动化智能生产线可靠性具有通用性。

| Abstract: | The three-dimensional material warehouse unit is an important sheet metal storage center in the sheet metal automatic intelligent production line. Its reliability is directly related to the reliability of the sheet metal automatic intelligent production line. Therefore, failure mode and effects analysis (FMEA) for the mechanical system of the three-dimensional material warehouse unit of the sheet metal automatic intelligent production line is very important. Aimed at the problem of lack of function and failure causality analysis in traditional FMEA, maintenance aware design environment (MADe) software is used to perform functional analysis and failure data analysis for the mechanical system of the three-dimensional material warehouse unit, and establish the function model diagram of the three-dimensional material warehouse unit and the failure causality diagram of the mechanical system. On this basis, the fuzzy cognitive map (FCM) adjacency matrix of the mechanical system is constructed according to the functional model diagram of the three-dimensional material warehouse unit, and then the FMEA table of the mechanical system of the three-dimensional material warehouse unit is obtained through calculation. The FMEA analysis of the mechanical system of the three-dimensional material warehouse unit based on MADe software shows that this method is universal for improving the reliability of the sheet metal automated intelligent production line. |
