Estimation of Remaining Useful Life of Rolling Element Bearings Using Wavelet Packet Decomposition and Artificial Neural Network
TL;DR: Wavelet packet transform is used to extract signal features and artificial neural network is applied to estimate RUL of the REB and comparison of the experimental results with the output of the trained neural network shows enhanced prediction capability.
Journal ArticleDOI
Identification of Asynchronous Blade Vibration Parameters by Linear Regression of Blade Tip Timing Data
Journal ArticleDOI
Rolling element bearing diagnosis using spectral kurtosis based on optimized impulse response wavelet
TL;DR: In this paper, a frequency band which is related to the resonance of the bearing bearing was selected for envelope analysis of rolling element bearings (REBs) in order to select the frequency band for fault diagnosis.
Journal ArticleDOI
Remaining useful life prediction of ball-bearings based on high-frequency vibration features:
TL;DR: Applying the proposed feature shows more accurate estimation of the bearings’ remaining useful life, compared with two popular features in the time domain (RMS and kurtosis) for prognostic purpose.
Journal ArticleDOI
A comprehensive evaluation of the effect of defect size in rolling element bearings on the statistical features of the vibration signal
Abbas Rohani Bastami,Sima Vahid +1 more
TL;DR: A physical model with the ability of modeling naturally developed defects has been used for the simulation of the generated vibrations in the rolling element bearings and simple relations between the defect size and vibration features have been proposed.
