机械失效诊断递阶结构模型的建立

对于机械失效诊断提出可以根据设备中各零部件的二元关系，利用解析结构模型来建立阶递结构；该方法可以避免在建立故障树时下行法和上行法的繁杂的计算，较为简单地得到造成设备失效的层次关系，为设备维修提供一个清晰的概念，而且用这一方法可以加速计算机的自动建树．

SET UP MODEL OF HIERARCHICAL STRUCTURE IN DIAGNOSIS OF MACHINERY'S FAILURE

According to the binary relation,in the parts of equipment,utilizing the analytical structural model, we set up hierarchical structure to diagnose machinery failure. Themethod can avoid the complex calculation of Fussed -Vesely when we establish Fault Treeanalysis,simply obtain the series relation in equipment failure,supply a clear conception forequipment maintenance and in overhaul quickly auto-establish Fault Tree analysis by computer.
