Wavelet filter-based weak signature detection method and its application on rolling element bearing prognostics
TL;DR: In this paper, the performance of wavelet decomposition-based de-noising and wavelet filter based denoising methods are compared based on signals from mechanical defects, and the comparison result reveals that wavelet filters are more suitable and reliable to detect a weak signature of mechanical impulse-like defect signals, whereas the wavelet transform has a better performance on smooth signal detection.
Journal ArticleDOI
Robust performance degradation assessment methods for enhanced rolling element bearing prognostics
TL;DR: Enhanced and robust prognostic methods for rolling element bearing including a wavelet filter based method for weak signature enhancement for fault identification and Self Organizing Map (SOM)based method for performance degradation assessment are introduced.
