In this paper,<a href="http://www.christianlouboutinskodk.com" target="_blank" class="postlink">Christian Louboutin</a>, multi-resolution analysis of wavelet transform and extract the details of rubbing vibration signal components, the situation of different rubbing, rubbing the different levels of detail determines the distribution of the different signals, so the details of the signal energy distribution is different, the use of This feature can effectively diagnose the extent Rub. In addition, the use of the results of this analysis, no rubbing in the diagnosis and when the whole ring of rubbing achieved good results. 123456 Reference Zhang XD. Modern signal processing.
