事故树分析法在港机故障检测中的应用
Application of accident tree analysis in portmachinery fault detection
摘要
Abstract
Amethod based on accident tree analysis (ATA)was proposed to identify andprevent the potential hazards of the gantry crane.Theportal crane accident was seemed as a top event.Starting withtwokind of major accidents such ascollapse and falling,thereason that cause the top event was found and the accident tree wasestablishedby the layers of depth.According to thelogical relationship of each event in the accident tree,the Boolean method wasused to simplify the accident tree and the Algebraic expressions were got.Though using the qualitative analysis of fault tree,the minimum cut set of itwas obtained.Thenthe structural importantdegree of cut set,which easily cause the top event of firstorder,wascalculated and carried on the sorting.The results show that the risk resourceof accident hazards of portal crane are overload,welding crack,defects of designand manufacture installation and improper operation.The countermeasures of workingunder rated load,design and manufacture installationin strictaccordance with the national standardand periodicinspection are put forward to prevent this kind of accident to happen.关键词
