摘要
FMEA是把系统分割成子系统或原件,找出它们可能产生的故障和故障类型,然后进一步分析各种故障类型对工作人员造成的危害及整个系统产生的影响,以便管理者采取措施产生解决方法。通过FMEA分析方法,从物的不安全状态的角度,对煤矿胶带输送机进行了系统的分析。通过使用基于模糊集与灰色关联理论的FMEA评价改良方法,依据计算得出的灰色关联度,对不同故障类型风险进行排序。通过FMEA分析及评价结果,结合煤矿现有的隐患排查制度,形成了不同层级的隐患排查单。并依据煤矿目前的管理制度,提出了相应建议措施。
FMEA is a method that divide the system into subsystems or split into original, and identify the possible fault and fault type, then analyze the harm of various fault types on the staff and the impact on the whole system to take measures to solve them. By FMEA analysis methods, from the perspective of material insecurity, the article analyzed belt conveyor systematically. By using fuzzy set theory and gray relational FMEA evaluation improved method, based on calculated grey correlation, the article gave a sequence, and formed different levels hidden danger investigation from the result of FMEA analysis and evaluation and the system of hidden danger investigation in coal mine. Based on the current mine management and control measures, propose other measures were proposed.
