Descriptive Study of a Rotary Machine Affected by Misalignment and Imbalance Applying the Wavelet Transform

The study of the effects produced by both, imbalance and misalignment in rotating machines, allow identifying the effects produced by these two phenomena under normal operating conditions of the equipment. Initially, an analysis is carried out using the wavelet transform, through the application of the LabVIEW and Matlab software; the goal was to compare these results with those obtained with the application of the Fourier transform. Additionally, a subsequent comparison of the results is carried out as a consequence of an initial comparison with an antecedent, where the Cepstrum-Fourier transformer and the Wavelet transform were applied to verify the existence of faults in a rotating machine. The present work is developed in order to determine which of these two studies represent these effects of misalignment and imbalance in a clear, specific, and/or significant way.
