摘　　要：以舰船动力装置中的柴油主机滑油管路系统为研究对象,针对滑油系统故障诊断问题,分析了常见故障机理,建立了滑油系统常见故障的故障树结构,在此基础上构建了用于故障状态推理的贝叶斯网络模型,分析了滑油系统典型故障状态下的贝叶斯状态推理过程,为滑油系统的快速故障诊断提供了一种新的方法。Aiming at dealing with the fault status of lube system in power plant, common faults of the treestructure in the lube system was established, meanwhile, the Bayesian network model for fault state reason-ing was constructed and the procedure of Bayesian reasoning was analyzed deeply in typical state of lubesystem, through which a new method was provided to the fast fault diagnosis.
