摘要
抱索器是脱挂索道的重要部分,对索道的安全运行至关重要。故障树是可靠性分析中常用的方法,对这种新型抱索器开展故障树分析存在故障数据积累不足问题,为此采用将专家模糊语言值定量化,并对多位专家经验综合的方法,将定性数据转换为定量数据用于故障树分析。
As the joint of aerial carriage and the transport ropeway,safety of a detachable rope-holding clip(DRHC)is critical for passenger cableway.Fault tree analysis is extensively employed as an effective risk analysis technique,and its quantitative analysis requires a probability of the basic event.But there exists the data deficiency issue for DRHC fault tree analysis.The present study proposes an evaluation methodology of the fuzzy fault tree based on the aggregation,defuzzification,and conversion of different experts'linguistic assessment of probabilities.
