Abstract :

In this research, acoustic emission and viation technology was used to detect defects in the rolling elements be�s, using statistical techniques to analyze the time domain signal. To extract the well–established statistical parameters, Such as the RMS, peak level, crest factor and other features including kurtosis and skewness. This experimental study focused on the analysis of acoustic emission signals and acceleration to determine the presence of defects in the radially loaded be�. A defect of a certain size was seeded in the inner race and outer race of the test be�s. The results reveal that the AE technology is more effective in detecting be�s faults than that of the viation measurement, especially in the low frequency range
