Research on Identification of the Crack on Rotor Shaft

Abstract

Abstract:In the present research the crack identification in rotor systems is proposed based on Holospectrum. The purpose of the research is to detect not only the crack location on a rotor shaft, but also the crack type and the angle between two cracks on a rotor shaft. 3D Holospectrum is introduced to detect crack location on the shaft, and the 2D Holospectrum to detect the crack type and angle between two cracks. The proposed technique was validated through numerical simulations on the rotor system with a two cracks.
