The coupling between longitudinal, lateral and torsional vibrations is studied together for a
rotating cracked shaft. These coupling mechanisms have been studied here with a response …

Rotor crack occurs frequently in rotating machinery. It is of great significance to study the
vibration mechanisms of the cracked rotor-bearing system, which can provide proofs for …

The influence of the presence of transverse cracks in a rotating shaft is analyzed. The paper
addresses the influence of crack opening and closing on dynamic response during …

Fatigue cracking of the rotor shaft is an important fault observed in the rotating machinery,
which can lead to catastrophic failure. The paper addresses the influence of the crack …

This paper presents a novel way to detect fatigue transverse cracks in rotating shafts. The
proposed detection methodology exploits both the typical nonlinear breathing phenomenon …

The stability of a rotor system presenting a transverse breathing crack is studied by
considering the effects of crack depth, crack location and the shaft's rotational speed. The …

Damages in rotor systems have severe impact on their functionality, safety, running
durability and their industrial productivity, which usually leads to unavoidable economical …

In this study the authors propose to take into account the nonlinear effects induced by the
presence of a transverse crack to carry out vibratory monitoring and detect transverse cracks …
