Abstract

Journal of Vibration and Control, Ahead of Print.
The contact interface of gas turbine rod-fastened rotors is complex, leading to a weakening of the overall structural continuity and enhancement of nonlinear characteristics. The structural form of the rod-fastened rotor can induce some special failures, ...
