ABSTRACT
CBM (Condition based maintenance) is an effective approach to reduce the fault rate and thus avoid the occurrence of serious failure. Quantitative identification of bearing fault severity is the basis of CBM for bearings. The vibration signals will exhibit nonstationarity and nonlinearity in the presence of bearing faults. Taking into account the mean value and the variations of the entropies over multiple scales, a new index termed Partial Mean of Multiscale Entropy (PMME) is constructed to quantitatively describes bearing fault severity. Experimental results verify that the new index is able to detect incipient bearing fault in a timely fashion and can trend the fault development well.
