Feature Clustering Analysis Using Reference Model towards Rolling Bearing Performance Degradation Assessment

<div>The envelope spectrums in the test for bearing 2# of testing 2 at different operating moments: (a) the trigger value of the proposed method at point 502, (b) the trigger value of the compared method at point 651, and (c) the breakdown value of the whole-life bearing at point 960.</div>
