摘要：
The detection and monitoring of slant crack in the rotor system using mechanical impedance was discussed. The effect of a slant crack parameters on normalized impedance was found to be the same as transverse cracks. The changes in rotor impedance due to cracks were found to be significant, as compared to that of natural frequencies of the rotor-bearing system. It was suggested that the measurements of mechanical impedance can also be used for slant crack detection and monitoring.
