摘要
介绍了近年来国内外液压系统故障树分析(FTA)的研究现状,着重总结了基于模糊数和基于T-S模型的液压系统模糊FTA方法,评述了二态系统、多态系统重要度和模糊重要度等重要度分析方法,归纳了基于FTA的故障诊断专家系统和故障搜索方案等故障诊断优化方法,指出借鉴其他系统的FTA方法并移植到液压系统中、将现有的FTA方法与其他算法相融合是液压系统FTA领域今后的发展趋势。
The current research of Fault Tree Analysis（FTA） of hydraulic system at home and at abroad in recent years was introduced.The fuzzy FTA methods of hydraulic system based on fuzzy numbers and T-S model were summarized especially.The importance measures such as binary-state system and multi-state importance and fuzzy importance were reviewed.The optimization of fault diagnosis methods based FTA such as fault diagnosis expert system and fault search strategy were summed up.It was pointed that the developing trends of FTA field of hydraulic system were bringing FTA methods of other system into hydraulic system and combining existing FTA method with other algorithms.
