TL;DR: In this paper, two different approaches: equivalent loads minimization and vibration minimization method are applied for the identification of unbalance fault in a rotor bearing system by minimizing difference between equivalent loads estimated in the system due to the fault and theoretical fault model loads.

TL;DR: In this article, the authors discuss very recent developments of the research on cracked rotors, including the inverse problem of the identification of cracks in rotating machinery, and the aim of this paper is to discuss the importance of fatigue crack in the shaft.
Abstract: An important rotor fault, which can lead to catastrophic failure if undetected, is fatigue crack in the shaft. Cracked rotating shafts have been the subject of studies and investigations for more than four decades, with some review papers published over this period. The aim of this paper is to discuss very recent developments of the research on cracked rotors, including the inverse problem of the identification of cracks in rotating machinery.
