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。 The rotor is the core component of the rotating machinery and equipment, and a diagnosis expert system is established for the rotor fault. Expert system includes knowledge acquisition system, knowledge base, reasoning machine and input / output system. The knowledge base and inference mechanism have become the core of the expert system. The system builds the knowledge base according to the structure of the fault tree and adopts the depth-first search strategy in the inference engine. The expert system uses the object-oriented programming method to realize the diagnosis of the common faults of the rotating machinery rotor system.
