A multi-crack identification algorithm has been developed based on the forced response from a shaft. Transverse vibrations of a cracked shaft in the two orthogonal planes are analyzed. The presence of cracks in a shaft introduces a local slope discontinuity in the elastic line of the shaft. This slope discontinuity is estimated by approximating the forced response of shaft at consecutive measurement...
The identification of multiple cracks in a shaft is still a real challenge. In the present work, a two-stage identification methodology has been developed, which identifies a number of cracks, their locations on a cracked shaft and its sizes. The methodology uses transverse forced responses of the shaft system at different frequencies of a harmonic excitation. In the first stage, a multi-crack detection...
