摘要
This note presents a brief experimental investigation on the crack propagation monitoring in rotating shafts supported by fluid film bearings using high-frequency acoustic emission signals. Wavelet decomposition of the acoustic emission signals is performed for six shafts with different crack depths rotating at subcritical and supercritical speeds. The median absolute deviations of the signals are employed in an attempt to relate the crack depth with the values of the statistical median deviation. The preliminary experimental results show that the median absolute deviation can be an adequate statistical function to analyze the crack propagation in high-speed rotating shafts.
