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 …

Blade loss from a running turbofan rotor will introduce sudden unbalance into the dynamical
system, and as a consequence leads to the rub-impact, the asymmetry of rotor and a series …

Double-clamped bistable buckled beams demonstrate great versatility in various fields such
as robotics, energy harvesting, and microelectromechanical system (MEMS). However, their …

Fan blade off occurring in a running rotor of the turbofan engine dual-rotor system will cause
a sudden unbalance and inertia asymmetry, which results in large impact load and …

It is well known that the sudden unbalance is harmful for rotor systems, since it is in huge
amount and has a strong impact. Thus, it is difficult to identify the unbalance from the sudden …

The present work demonstrates the effectiveness of an active magnetic damper (AMD) in
improving the vibration characteristics of an overhung rotor system (ORS) considering the …

The loss of fan blades in an aeroengine, or fan‐blade out (FBO), is a type of accident that
causes a sudden imbalance and large impact load, which leads to complex vibration of a …

Overhung rotors are widely used in the industrial field. However, compared with normal
structure rotors, the prediction and control of overhung rotors cannot achieve good …

Considering turbine blade-off event in the typical turboshaft engine, dynamic model of the
rotor-support system is established, and the modal characteristic, as well as vibration …
