【摘要】：三峡升船机驱动系统故障模式的危害性直接关系到升船机的安全运行。为判定故障模式危害度等级,根据运行情况,结合同类型升船机,选取了驱动系统的5类故障模式;引入恢复效度的概念,运用德尔菲法对恢复效度、发生频度、严酷度和可探测度进行等级划分并利用AHP法确定各评估指标的权重;最后通过TOPSIS方法建立了数学模型,对三峡升船机驱动系统故障模式的危害性进行了分析、排序和验证。结果表明:恢复效度与故障危害性关联最为密切,齿轮和齿条故障对升船机的危害性最大,其次分别是减速器、同步轴系统、小齿轮托架以及万向轴等。此方法为有针对性的制定相关弥补措施和对策提供了依据,也为三峡升船机其他关键机构失效危害性分析提供了参考。
[Abstract]:The harmfulness of the fault mode of the three Gorges ship lift drive system is directly related to the safe operation of the ship lift. In order to judge the damage degree of fault mode, combined with the same type ship lift, five kinds of fault modes of the drive system are selected according to the operation situation, the concept of recovery validity is introduced, and the recovery validity is analyzed by Delphi method. The severity and detectability are classified and the weight of each evaluation index is determined by AHP method. Finally, the mathematical model is established by TOPSIS method, and the harmfulness of the fault mode of the three Gorges ship lift driving system is analyzed, sorted and verified. The results show that the recovery validity is most closely related to the fault hazard, the fault of gear and rack is the most harmful to the ship lift, followed by the reducer, the synchronous shaft system, the pinion bracket and the universal shaft, etc. This method provides a basis for making relevant remedial measures and countermeasures, and also provides a reference for the failure hazard analysis of other key mechanisms of the three Gorges ship lift.
