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 …

The vibration phenomena which occur in rotary machines, such as power plants, can result
in catastrophic consequences. Any failure in any power plant section can result in extended …

This paper aims to study the nonlinear steady-state response of a dual-rotor system with rub-
impact fault subject to unknown-but-bounded (UBB) uncertainties. Mathematical modelling …

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 …

Abstract Fan Blade Out (FBO) from a running rotor of the turbofan engine will not only
introduce the sudden unbalance and inertia asymmetry into the rotor, but also apply large …

With the development of the aero-engine rotor system towards accurate modeling, it is
necessary to establish a general rotor system model considering many important strong …

A dynamic modeling method is proposed for shaft-disk-drum (SDM) rotor systems with
elastic connections and supports, upon which coupling vibrations of disk, drum and shaft are …

Rub-impact fault is one of the most common and severe failure modes for rotating
machinery. Disclosing the changing dynamic in rub-impact fault signal could provide a basic …

For theoretical and experimental research on the fixed point rubbing of aero-engine, a dual-
rotor system capable of describing the mechanical vibration resulting from two imbalances …

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 …
