模糊关联方法在齿轮箱故障诊断中的应用

The application of illegibility associated degree method in diagnosis of gear box failure

模糊关联度故障识别方法是运用灰色系统理论与模糊数学隶属函数相结合 ,克服了故障诊断的模式向量中参数量纲不同、数量级差异的缺点 ,综合了灰色系统理论和模糊理论的优点 ,使故障诊断识别的多参数法更加完善。但此种方法的关键是隶属函数建立的可靠性 。

Failure identify method of illegibility associated degree is united with Gray system theory and subjected function in Illegibility mathematics,which conquers the disadvantage of difference of parameter dimension and magnitude,and integrates the virtue of Gray system theory and Illegibility theory,makes multi-parameter failure diagnosis method more perfect.The crisis of the method to the accuracy of the failure diagnosis is related to the credibility of the founded subjected function.
