EXPERIMENTAL INVESTIGATION FOR FAULT DI AGNOSIS BASED ON FFT AND WAVELET TRANSFORM

By MIHAIL PRICOP

Abstract

Belts are components of the mechanical systems of rotation commonly used for mechanical \ud power transmission and changes in rotational speeds in the shafts. Various failures of the drive belts (foot \ud shear, tooth wear, hollowed teeth, back cracks) are common in rotating machines and can cause economic \ud losses. To increase efficiency, reliability and safety of the machines the use of new fault diagnosis \ud techniques of belts, identification and classification is required. In this paper Fast Fourier Transform (FFT) \ud and Wavelet transform complementary methods are used for fault monitoring of drive belts, analyzing in this \ud way the limitations and advantages of using these methods. Experimental investigations for the fault \ud diagnosis of drive belts are made using experimental platform and Bruel & Kjaer equipment for measuring \ud vibration and PULSE and MATLAB software for recorded signal processing. The results were analyzed and \ud presented
