机械故障诊断中常用解调方法的比较及应用

The Comparison and Application of Envelope Demodulation in Machine Fault Diagnosis

在介绍了解调在机械故障诊断中应用的基础上 ,对基于Hilbert变换的包络解调法和检波解调法的原理及实现方法进行了比较 ,并且给出了用包络解调法对滚动轴承进行诊断的实例 ,取得了满意的效果。

In this paper, two methods of demodulation are described. After comparing each other, an experiment result with demodulation based on Hilbert Transformation is presented. The result shows that demodulation can be used in ball bearing fault diagnosis effectively.
