Vibration Analysis of Cantilevered Curved Plates Using a New Cylindrical Shell Finite Element
Abstract
The stiffness and mass matrices for a relatively simple finite cylindrical shell element are presented. The element has 28 degrees of freedom corresponding to the seven generalized coordinates at each corner. All six rigid body modes for the element are adequately represented by this model. The element is used to predict the vibrations of a curved fan blade, and the results are verified experimentally. It is found that a 4 x 4 grid of the finite elements is sufficient to predict the first twelve vibration frequencies for the fan blade to within ten percent. The agreement between experimental and theoretical mode shapes is generally very good.
