Some Topics about Nonlinear Rolling of Ships

A summary of the recent research situation and the discussion on some nonlinear problems about rolling of ships in waves are presented in this paper. Firstly, t he causes and the factors leading to the nonlinear ship motion are stated briefl y. Then the typical analytical models employed, the principal achievements at ho me and abroad and the prospects of the research works on nonlinear ship rolling are reviewed in detail in three aspects: large amplitude ship rolling; the coupl ing of rolling and heaving, and the coupling of rolling and pitching. Finally th e tendency of evelopment for nonlinear rolling of ships in waves is predicted. A nd the topics that should be studied and explored in depth in future researches on the nonlinear dynamics of ships in regular and random waves are suggested.
