Abstract |
The bearing fault is the most common in the rotating machines faults. Envelope analysis for rolling element bearing diagnostics has gained in the last years a leading role among the different digital signal processing techniques. This paper deals with the use of a simple and effective signal processing technique of square and Hilbert-based envelope analysis for detecting rolling element bearing faults. This paper also compares the bearing fault detection capability obtained with square and Hilbert-based envelope analysis. For this purpose additional white Gaussian noise (AWGN) and random noise are used with different SNR. Simulation results show that the noise sensitivity of the Hilbert-based envelope is higher than that of the square envelope. Square envelope shows steady in response to both AWGN and random noise. Keywords- Hilbert transform, squared envelope, bearing faults, Noise analysis, SNR | |||||||||
