WAVELET ANALYSIS FOR VIBRATION SIGNALS

Abstract

This paper presents an alternative method to classical Fourier transform approaches used in data analysis. In this manner, application of Continuous Wavelet Transform (CWT) was introduced for vibration data which is collected by an accelerometer replaced on an induction motor. Hence, related results were indicated as properties of the vibration signal and additional information was extracted from the raw data using the time-scale analysis. This extracted information was represented in high frequency region of the original data which is defined between 2 and 4 kHz.
