Abstract:
The
character of vibration signal caused by failed bearing is analyzed.
Based on wavelet packets algorithm without frequency band derangement, a
signal character extraction method of rolling element bearing failure
measurement is proposed. The character function portrays distribution
condition of failure impact precisely. The practical example shows the
reliability and the method has a high signal-to-noise ratio.
Key words:
Rolling element bearing Wavelet packets Failure Signal
