Abstract:

A finite element model is developed for the Class IV flextensional underwater transducer shell. The stiffness and mass matrices for a finite cylindrical type shell element of linearly varying radius of curvature are presented. The element has 36 degrees of freedom corresponding to the nine generalized coordinates at each node. All six rigid body modes for the element are adequately represented by this model. The element is used to predict the free vibrations for the Class IV flextensional underwater transducer shell, and the results are verified experimentally.
