The Dynamic Calculation of Lateral Bending Moments on Ships in Oblique Waves

摘要

The work is aimed at improving and extending the dynamical method for calculating lateral bending moments on ships in oblique waves developed on this project (AD-270 240) previously. The theoretical framework is first restated in a more general form. The equations of motions allow for three degrees of freedom, and all inertia, damping and cross-coupling terms. The bending moment equation is based on the lateral forces used to determine the motions. A computer program, which permits changes in the theory to be made easily, is then prepared to carry out the calculations.
