The Free Vibration Behaviour of Ring Stiffened Cylinders - A Critical Review of the Unclassified Literature.

Abstract

The free vibration characteristics of a submarine hull have an important influence on the noise signature. A submarine hull, or portion of one, can frequently be idealised as a ring stiffened cylinder subjected to external loading from the surrounding water, for the purposes of vibration analysis. The modal behaviour of ring stiffened cylinders is reviewed, including the effect of external pressure loading and added mass effects from surrounding fluid. The existing unclassified literature is inadequate in its coverage of the problem and these shortcomings are discussed, in order to identify the requirements for further work in order to be able to satisfactorily analyse a submarine hull structure.
