Vibration Signal Separation Technique by Using the Combination of Adaptive Filter and Hilbert Transform for Defect Machine Component in Rotating Machinery

摘要

This paper focused on enhancement defect signal by separating the unwanted signal by using combination of Adaptive Filter and Hilbert Transform. This combination is performed via simulation as well in experimental work. A growth index is introduced to serve as indicator to verify the fault detection capability. The result of this combination is compared with previous approach which are combination between wavelet packet and Hilbert Transform. The results showed that the unwanted signal is successfully separated, and sign of failures is greatly enhanced.
