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 ...

Abstract: The ball bearings of an aeroengine are key parts that frequently fail, and it is very important to effectively carry out fault diagnosis of the ball bearings. However, in the present research work, the ball bearing faults ...
