| 摘 要： | 提出一种基于T-S模糊故障树分析的故障搜索策略。以某型液压载重车支腿液压系统故障树为例,在给出T-S模糊故障树基本事件的T-S关键重要度概念和计算方法的基础上,综合考虑基本事件的T-S关键重要度和搜索费用等因素,采用逼近理想解排序法(TOPSIS)计算出故障方案的搜索顺序。该方法克服了传统故障树分析方法在故障搜索中二态假设的局限,分析了在不同顶事件故障程度的条件下的故障搜索策略,增加了故障搜索结果的准确度,提高了故障诊断的可行性。

| Abstract: | A fault search strategy is proposed in this paper based on T-S fuzzy fault tree analysis.A fault tree of outrigger hydraulic system of a certain hydraulic truck is illustrated when simultaneously considering the T-S importance and search cost of basic events based on the given concept and calculation of T-S importance.TOPSIS(Technique for Order Preference by Similarity to Ideal Solution) is used to evaluate the search order of fault alternatives.The limitations of binary-state hypothesis of traditional faul... |
