摘要：
The traveling wave resonance characteristics of a high-speed rotating thin cylindrical shell were studied under different boundary conditions based on the transfer matrix method. Firstly, the vibration differential equations of the rotating thin cylindrical shell were set up based on Love's shell theory considering the effects of centrifugal forces, coriolis forces and inertial forces. Secondly, with the state vector expression between sub-segments, the transfer matrix method was introduced to derive the overall transfer matrix of the structure. Finally, its resonance characteristics were solved with the high-precise integration method under simply supported-simply supported, clamped-clamped and clamped-free boundary conditions. The example's results showed that the transfer matrix method is suitable for solving the resonance characteristics of the high-speed rotating thin cylindrical shell, and the vibration modes in circumferential direction are the main contributors to the resonance of the shell under three boundary conditions; there is only one resonance rotating speed point when the resonance margin is less than 10% under the operating rotating speed and the first octave excitation, but the resonance rotating speed points under other octave excitations are not within the safe margin range. © 2016, Editorial Office of Journal of Vibration and Shock.
