Vibration characteristics of rotating cylindrical shells

Abstract

A vibration analysis of rotating thin-walled cylindrical shells having various end conditions is presented. Rayleigh-Ritz method is used to derive the governing equations by using the Flugge type strain-displacement relations. More shapes are assumed to be satisfied with the effect of rotation as well as the boundary conditions. Natural frequencies are calculated for clamped-clamped end with various rotating speed. The effect of rotation causes the natural frequency of the stationary case to split into higher and lower parts and develops the travelling waves. Forced vibrations of rotating cylindrical shells is investigated. Dynamic response of the shell is derived when the harmonic exciting force is applied to the shell radially.
