压缩机运行状态的灰色关联度分析

Gray Cognate Analysis of Comprossorq′s Fault Diagnosis

讨论了灰色关联度分析法在全封闭小型压缩机状态检测中应用的有关问题；提出了灰色关联度法在多参数故障诊断中应用时特征参数的选择及处理方法．通过压缩机诊断实例说明了灰色关联度法的使用效果，并在与其它诊断方法比较的基础上，总结了灰色关联度法的特点．

This paper presented the application of gray cognate analysis in full closed small comprossor′s fault diagnosis. The choise of characteristic parameters and its processing method, used in the application of gray cognate analysis to multi parameter fault diagnosis, were discussed. The effect of gray cognate analysis method was proved through comprossor fault dignosis experiments. Based on comparing with other diagnosis methods, the advantage of the gray cognate analysis method was summarized.〖KH*2D]
