Traveling Wave Vibration of Rotating thin Circular Cylindrical Shell

摘要

In this paper, the vibration characteristics of the rotating thin circular cylindrical shell subjected to the radial excitation are presented.Based on the Love's shell theory, the governing equation of the rotating thin circular cylindrical shell is derived by using the Hamilton's principle.Then, the amplitude-frequency responses for traveling wave vibration of the circular cylindrical shell are investigated.The results indicate that there exists the traveling wave vibration for the rotating thin circular cylindrical shell, namely: the forward wave and the backward wave.The effects of the damping and excitation on the amplitude-frequency response are analyzed.
