Machinery fault diagnosis has progressed over the past decades with the evolution of
machineries in terms of complexity and scale. High-value machineries require condition …

The rotor–stator rubbing in rotating machinery generated as a consequence of rotor
imbalance, shaft misalignment, and casing deformation is a potential threat to the machinery …

Free vibration behaviors of a functionally graded (FG) disk-shaft rotor system reinforced with
graphene nanoplatelet (GPL) resting on elastic supports are investigated in this paper. The …

Inter-shaft rub-impact, ie, the rub-impact between two rotors, may occur in an aeroengine
dual-rotor system. This paper represents the first attempt to investigate the nonlinear …

This paper focuses on the dynamic responses of whole aero-engine with blade-casing
rubbing. The vibration response of casing is simulated and the dynamic behaviors of casing …

Condition monitoring is crucial for a rotating blade working in harsh conditions. Blade tip
timing (BTT) is a potential technique for operational blade health monitoring owing to its non …

The self-powered sensing technology based on gravity-rotation-excited vibration energy
harvesting (GRE-VEH) enables information acquisition directly from rotatory machines …

There exists a lot of research on the breathing-crack induced nonlinear vibration for beam-
like structures. To the best of our knowledge, these studies mainly focus on the non-rotating …

In the current work, a unified modeling approach is developed for rotating flexible shaft-disk
systems under general boundary conditions to investigate the general coupling vibrations of …

A rub-impact can bring the impact load and friction force onto the rotor, and in the meantime,
it can also produce the additional effect of changing the stiffness of the rotor system. Past …
