摘要
在分析往复锯床间隙处的不同位置特性的基础上,利用提升小波变换进行复合特征提取,并用灰色关联度对特征向量进行识别,为往复机械不停机诊断提供一种有效的方法。
On the basis of analyzing different position features of clearance,the article makes use of micro-wave conversion for distilling compound features,and identifies feature vector with gray relevancy,thus providing an effective way for the non-stop diagnosis of reciprocator.
