摘要

Aiming to break through the assumption that ship's transverse (mainly roll) and longitudinal (mainly pitch and heave) motion are not coupled in traditional sea-keeping study, the mathematical model to study coupling coefficients of transverse/longitudinal motion was proposed, and ship's roll, pitch/heave and roll/pitch/heave coupling motions in oblique regular wave were numerical simulated by CFD method. Based on the simulation results, the coupling effect of transverse and longitudinal motions was analyzed. The results show that: the coupling effect exists between ship's transverse and longitudinal motions, which varies with the ratio of wave length and ship length, and compared to uncoupling data, the change of ship's hydrodynamics, amplitudes of motion and Respond Amplitude Operators (RAO) is up to 10% at maximum.
