模糊数学在设备故障诊断中的应用

The Application of Fuzzy Mathematics in Fault Diagnosis of Equipment

介绍了用于故障诊断的模糊关系矩阵的建立方法，包括故障征兆论域、故障原因论域以及它们之间隶属关系的确定；在此基础上给出了基于模糊关系矩阵的故障诊断的一般方法；最后，结合作者的实际工作，介绍了一个诊断实例。

The method how to build a diagnosis matrix,including the determination of the fault omen field,the fault reason field and the subordinate relation between the two fields is,in the first place,introduced.Then,on the basis of the introduction,the general method of fault diagnosis based on the fuzzy relation matrix is given.Finally,introduce a concrete instance from our practical research,and offer a few proposals for the improvement of the diagnosis method.
