摘要/Abstract

摘要： 为有效抑制垂直升船机液压系统故障传播,基于液压系统诸结构间的相互关联性及链式连锁特点,建立故障传播模糊Petri网(FPN)模型。基于FPN基本原理,抽象表达液压系统故障传播过程;分析垂直升船机液压系统失效模式,理清故障状态间前后集的逻辑关系,建立液压系统故障传播FPN;利用故障演变规则,模糊推理液压系统故障传播路径。结合三峡升船机进行实例分析。结果表明,其液压系统故障最可能的传播路径为:控制阀损坏-系统无法保压-启闭油缸失效-船厢门液压启闭机故障-系统退出工作。

Abstract: Taking into account the correlations and chain-interloacking actions between the structures in an existing vertical ship lift hydraulic system, an FPN model was built for fault propagation to effectively reduce system malfunction in the vertical ship lift. Firstly, the process was preseated abstrictly with the applying of basic variables in FPN, failure propagation in the hydraulic system on the basis of the basic principle of FPN. The fault modes of the hydraulic system were analyzed. An FPN was stablished after clarifying the logical relationship between the fault locations. finally, the fault propagation path was deduced fuzzily using the transition rule. The Three Gorges ship lift was analyzed by using the method. The results indicate that the most likely propagation path to bring in the failure of vertical lift ship hydraulic system is the damage to the control valve,the failure of hoist, the failure of pressure keeping,failure of pressure keeping, may further bring failure of hydraulic hoist of ship carriage, and the whole system may stop working.
