In rotary machinery, bearings are susceptible to different types of mechanical faults, including ball, inner race, and outer race faults. condition-based monitoring (CBM), several techniques have been proposed in fault diagnostics based on the vibration measurements. For this paper, we studied fractal characteristics non-stationary signals collected from under health conditions. Using detrended...

Rolling element bearings are commonly used in rotary mechanical and electrical equipment. According to investigation, more than half of rotating machinery defects related bearing faults. However, reliable fault detection still remains a challenging task, especially industrial applications. The objective this work is propose an adaptive variational mode decomposition (AVMD) technique for non-sta...
