... as a multi-degrees-of-freedom model with the Rayleigh damping formulation. Then, the nonlinear damping curves are extracted from the original vibrations by using Morlet wavelet transform. During the laboratory experiment, the model was validated on a full-size winding model, and the free vibrations from...

... measured on bearings by discrete wavelet transform and subsequently performs the Fourier transform on the wavelet coefficients. The effectiveness of such a unified technique is demonstrated through experimental case studies, which confirmed its advantage over the wavelet or Fourier transform techniques...
