Aplicación de Transformadas Tiempo-Frecuencia al Diagnóstico de Fallas en Máquinas Rotatorias

Abstract

This paper deals with the joint time-frequency distributions applied to measured vibrations on rotating machines for evaluating its mechanical condition. The use and advantage of applying the Short Fourier Transform, the Wavelet Transform and Pseudo Wigner-Ville Transform is explored through the analysis of non-stationary and amplitude and frequency modulated vibrations generated by some faults on the machines.
