针对液压油缸故障树分析时存在的故障数据获取不足以及传统分析方法的限制,提出了基于T-S模型的液压油缸模糊故障树分析方法,对已建立的液压油缸T-S模糊故障树进行分析.分析过程中,采取将底事件的模糊失效率替代为其故障概率的方法,同时将其故障程度用模糊数来表示﹒对液压油缸T-S模糊故障子树进行实例分析,计算并分析所建立的液压油缸模糊故障子树的各故障分析数据.

According to the lack of fault data acquisition and the limitation of traditional analysis methods in the analysis of hydraulic cylinder fault tree, a fuzzy fault tree analysis method for hydraulic cylinder based on T-S model is proposed, and the established hydraulic cylinder T-S fuzzy fault tree is analyzed. In the process of analysis, the fuzzy failure rate of the bottom event is replaced by the failure probability, and the fault degree is expressed by fuzzy number. Example of fault tree analysis of hydraulic cylinder fault sub-tree is given for illustration, and the fault analysis data of ...
