Abstract: The problems of the vibration of rotating laminated cylindrical shells are solved by using finite element method. The effect of Coriolis accelerations, centrifugal forces, pre-stressing and geometric nonlinear due to large deformation are considered in this model. By calculating two cylindrical shells with different ordering of the laminates ( and ), the effects of rotating speed、geometric nonlinear and ordering of the laminated on the natural charac-teristics of cylindrical shells are discussed in detail.
