Equivalent Circuit for a Vibrating Beam Which Includes Shear Motions

Abstract

It has been demonstrated that the whipping modes of a ship are approximately the same as those computed for a tapered continuous beam, provided shear motions as well as bending motions are included in the computations. It is here shown that such a beam can be represented by an electric circuit made up of lumped passive components. Given such a circuit, it is then possible to determine experimentally the gross responses of the ship to any arbitrary excitation. Variation of responses with changes in the design of a ship can also be studied.
