Disc-Rotor System, FEM Investigation


A theoretical analysis of the dynamics of a rotor-bearing system with a transversely cracked rotor is presented. The rotating assembly is modeled and the presence of a crack is taken into account. Rotor dynamics is the study of vibrational behaviour in axially symmetric rotating structures. The vibration in rotating machinery is mostly caused by unbalance, misalignment, mechanical looseness, shaft crack, and other malfunctions. A strong interest has developed within the past several years in the dynamic behavior of turbo machinery with cracked shafts. An excellent review of the field of the dynamics of cracked rotors and of different detection procedures to diagnose fracture damage has been presented. In literature, several studies are available for cracked rotor systems, and few authors have addressed the issue of multi-cracked rotor system. These statistics indicate that this is a very dynamic area of research, and the main focus of present article seeks to provide comprehensive review of previous and recent research work published on dynamic analysis of a cracked rotor.
