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.

“…The influence of a breathing crack on the vibration of a rotating shaft has been in the focus of many researchers. Comprehensive literature surveys of various crack modelling techniques, system behaviour of cracked rotor and detection procedures to diagnose fracture damage were contributed by Sabnavis et al [2] and Kumar and Rastogi [3]. More recent studies have been reviewed by Bachschmid et al [4].…”

Abstract. The presence of a crack reduces the mean stiffness of the rotor system and introduces a stiffness variation during the revolution of the shaft. How the variable part of the rotor stiffness varies between a minimum (for a closed crack) and a maximum (for an open crack), depends on the so-called breathing mechanism. The breathing mechanism is known when the open and closed parts of the cracked area are known for all angular positions of the rotor. Here, finite element (FE) and multi-body simulation (MBS) is introduced. It is based on a representation of the fracture process zone by a cohesive zone model (CZM). First, the cracked elastic shaft with various relative crack depths is modelled by FE. As a second step, the FE model of the shaft is transferred into an MBS model in order to
