摘要
提出一种基于故障树分析的深潜救生艇对口救生作业安全性评估方法。采用专家评估和模糊集理论相结合的方法得到故障树中基本事件发生的模糊概率,然后进行故障树定性和定量分析。以水下作业机械手系统故障分析为例,对上述的安全性评估方法做了简要阐述与讨论。
From the point of view of fault tree analysis, a new safety assessment method for Joint in DSRV＇s Lifesaving is proposed in this paper. Using experts＇ estimation and fuzzy sets theory, the fuzzy failure rates of the basic events in fault tree are derived, and then fault tree analysis （FTA） is performed qualitatively and quantitatively. The interfacing manipulators＇ fault tree analysis is taken for example in order to introduce the new method summarily. At last, the new method for safety assessment is briefly discussed.
