摘　　要：转子是旋转机械设备的核心部件,针对转子故障建立诊断专家系统进行研究。专家系统包括知识获取系统、知识库、推理机和输入输出系统。其中知识库和推理机构成了专家系统的核心。系统依据故障树的结构组织建立知识库,并在推理机中采用了深度优先搜索策略。专家系统采用面向对象的程序设计方法,实现了对旋转机械转子系统常见故障的诊断。Rotor is the kernel part in rotary machinery. How to set up a diagnostic expert system aiming at rotor faults is studied. The expert system includes knowledge acquisition system, knowledge base, inference engine and input/output system. The kernel is knowledge base and inference engine in expert system. The knowledge base is built according to the structure of a fault tree and searching strategy of depth priority is adopted in the inference engine. Objective-orienting program design method is adopted in the expert system. The diagnosis for common failures of the rotor system in rotary machinery is achieved.
