Modeling and dynamic analysis for rotors with curvic-coupling looseness

The joint structures, such as flanges with bolts and curvic-couplings, are commonly applied in aero-engine rotors. Those joints tend to loosen when subjected to heavy load, and the local deformation of the joints can induce nonlinearities to the rotor and further affect its dynamic characteristics....
