- Abstract
This paper presents a new methodology for degradation assessment in bearings with outer race fault. The novelty of the paper is the application of the Lempel-Ziv complexity (LZC) to the node of maximal energy from the wavelet package transform of the raw vibration signal. The objective of the paper is to develop a methodology for outer race fault bearing severity assessment and to show how the extracted feature LZC follows monotonically the bearing degradation. The proposed methodology is compared with LZC and kurtosis extracted from the raw vibration signal and with kurtosis extracted from the node with maximal energy.
