Abstract :
The present work shows that the Wigner-Ville and Choi-Williams distributions are useful to determine the proper operation of rotating equipment. As an example, the bearing diagnosis obtained by analyzing real sound samples using ultrasonic technology will be presented to highlight the flexibility of the proposed approaches for industrial machinery monitoring.
