THE INFLUENCE OF ROTATION ON VIBRATION OF A THICK CYLINDRICAL SHELL

The problems of the vibration of rotating cylindrical shells are solved by using nine-node super-parametric finite element with shear and axial deformation and rotatory inertial. The non-linear plate-shell theory for large deflection is used to handle the cylindrical shell before it reaches equilibrium state by centrifugal force. The effects of Coriolis acceleration, centrifugal force, initial tension and geometric non-linearity due to large deformation are considered in this model. Eight categories of mode of a rotating thick cylindrical shell are presented. The effects of rotation on different three-dimensional modes of cylindrical shell are discussed in detail.
