机械故障诊断中的模糊识别法

A Fuzzy Recognition Method for Mechanical Failure Diagnosis

所讨论的诊断方法是应用模糊推理和模糊识别理论，在判断故障产生的原因及程度两方面，进行了系统的阐述，给出了故障与征兆之间模糊关系的条件分布函数及其确定方法和模糊识别理论的数学模型．通过对牙轮钻头实验台振动诊断，结果表明该方法具有良好的可应用性。

The method which diagnoses the causes and degree of failure based on fuzzy logic and reconnition theory is presented. The mathematic model of fuzzy recognition and the conditional distribution function of fuzzy relationship between failure and symptom are given. The vibratory diagnosis for the test device of Rotary Blast Hole Drill shows that it possessed a good rationality as well as an availability.
