Contemporary aero-engines aim for enhanced efficiency and weight reduction. They are designed to increase rotor operational speed while reducing rotor bending stiffness. This may result in bending deformation in rotor systems within the operational s

As the efficiency of advanced aero engines improves, the operational speed of their rotors increases. This heightened operational speed makes the rotor dynamics highly sensitive to changes in the rotor’s mass asymmetry state, or unbalance state. Du

Elastic rings are common rotor supporting structure, which have been widely used in aeroengine rotor-support system. However, large inertia force and gyroscopic moment may occur during the operation of aeroengine, which may lead to contact between el
