摘要
Abstract
Based on the Fault Tree Analysis (FTA), the fault tree of twin-lift hydraulic hoist system for gate is established by analyzing system failure form, system structure and the logical relationship between the parts and the system and taking the faults as the top event. The qualitative and quantitative analyses are carried out through computing the minimum cut sets and the importance. The results show that the fault is mainly caused by the wear of hydraulic components and the jamming of valve spool. The study can provide guidance to routine maintenance and repair.关键词
