HULL VIBRATION OF CONTAINER SHIP

The hull vibration of the container ship has been studied theoretically and experimentally. A theoretical calculation of the coupled horizontal-torsional vibration, in which three kinds of torsional rigidities (St. Venant's torsional, Wagner's bending-torsional and Matsura's shear-torsional rigidities) are taken into account. Calculation has been developed and coded into a computer program. Vlasov's bi-moment is considered regarding the continuity of the section-force due to warping. The vibration tests have been carried out on two container ships, results of which have been compared with calculated ones and empirical formulae have been derived. The theoretical method can explain the phenomena observed on full scale ships, though future studies on the center of twist and other ship parameters are necessary to refine the method.
