采用人工智能专家系统计算机技术模拟故障诊断领域专家的推理思维方式, 对机械设备发生的故障实现迅速准确的

诊断,同时缩短故障停机时间具有重大意义。本文应用Visual prolog 语言,构造了转子系统故障诊断专家系统,提出了一阶谓

词逻辑子句表达知识的方法,建立了专家知识库。系统的推理机采用深度优先的推理策略。应用表明系统有效完成旋转机械

常出现的十多种故障的诊断,并运行可靠。-The computer technology of artificial intelligence expert system is being used to simulate inference and thinking mode in

the field of fault diagnosis. The fault which occurs to the mechanical device can be diagnosed rapidly and exactly. At the same time,

it also has a great significance for shorting the downtime. Applying the Visual Prolog language in this article, fault diagnosis expert

system for rotating machinery is constructed. The expert knowledge base is established by the expressing way using the first-order

predicate logic clause. The rule in Depth-First Strategy (DFS) is introduced in the system ’s inference engine. The system completes

effectively more than ten kinds of fault diagnosis that the rotating machinery often appears. The results show the operation is reliable

through the application.
