摘　　要：运用模糊故障树分析方法对摩擦式提升机滑动故障进行定量分析,得到了摩擦式提升机滑动故障的模糊概率以及导致滑动故障各底事件的模糊重要度,从而找出产生滑动的主要原因。其分析结果为提升机的维护、检修和提高提升机的工作可靠性提供了依据。In the paper,the quantitative analysis of the sliding accidents of frictions hoists is carried out with the fuzzy fault tree analysis method,from which the fuzzy probability of the sliding of hoists and the fuzzy impor-tance weight of each basic event that leads to the sliding are derived,thus the major causes of the sliding are figured out.The analysis results provide a reference for the maintenance and overhaul of hoists as well as the improvement of the operation reliability of friction hoists.
