Rolling Element Bearing Fault Diagnosis Using Laplace-Wavelet Envelope Power Spectrum
The bearing characteristic frequencies (BCF) contain very little energy, and are usually overwhelmed by noise and higher levels of macro-structural vibrations. They are difficult to find in their frequency spectra when using the common technique of fast fourier transforms (FFT). Therefore, Envelope...
