自动化立体料库机械传动系统FMEA分析

为了解决自动化立体料库在钣金自动化生产线中的可靠性问题，采用维护感知设计环境（MADe，maintenance aware design environment）对自动化立体料库机械传动系统进行了故障模式与影响分析（FMEA，failure modes and effects analysis）。通过标准化分类法，定义其机械传动系统的功能和故障，建立起机械传动系统模型；利用模糊认知图（FCM，fuzzy cognitive map）分析各故障的传播路径和影响，生成机械传动系统的FMEA结果。结果表明，主要故障机理为磨损、腐蚀和变形，主要故障原因为润滑不足、污染物的进入和载荷问题。由此提出一系列针对性的改进措施，提高了自动化立体料库的可靠性。

FMEA analysis of mechanical drive system of automatic three-dimensional material warehouse

To solve the reliability problem of automatic three-dimensional material warehouse in sheet metal automatic production line, failure modes and effects analysis(FMEA)of mechanical drive system of material warehouse was carried out using maintenance aware design environment(MADe). The functions and failures of mechanical drive system were defined through standardized classification, and the model of mechanical drive system was established. The propagation path and influence of each failure were analyzed using fuzzy cognitive map (FCM) to generate the FMEA result of mechanical drive system. The results show that the main failure mechanisms are wear, corrosion and deformation, and the main failure causes are insufficient lubrication, pollutant entry and load problems. Thus, a series of targeted improvement measures are put forward to improve the reliability of the automatic three-dimensional material warehouse.
