摘要
在建立舰船海上纵向补给装置液压系统故障树的基础上,对液压系统进行模糊故障树分析,采用参照函数为正态型的L-R模糊数来描述各底事件发生的概率,推导出液压系统不能正常工作顶事件发生的模糊概率及其隶属函数分布,为提高系统的可靠性、改进结构设计提供了理论依据。
Based on the fault tree of hydraulic system of ship astern replenishment system, the paper introduced a fuzzy fault tree analysis on hydraulic system, developed the probability of bottom events occurrence with normal type L-R fuzzy number, and provided the distribution of the membership function and fuzzy probability value of the top event when the hydraulic system cannot work properly. This provided the theoretical foundation for improving the structure design and increasing of the system reliability.
