Abstract: A new rotor–stator rubbing model considering the blade–casing rubbing fault is put forward in this paper. The model couples the rotor together with its suspension (ball or roller bearings), the disk, the (multiple) ...

Abstract: In this paper, the mechanism of the asynchronous vibration response phenomenon caused by the looseness fault in the aeroengine whole vibration system is investigated by numerical integration methods. A single degreeoffreedom ...
