规则斜浪中船舶多自由度耦合的参强激励横摇
Forced-parametrically excited rolling of ships with multi-degree-of-freedom coupled motion in regular oblique waves
摘要
Abstract
To research the forced-parametrically excited rolling of ships , a new coordinate transformation method on an instantaneous equivalent rotation matrix is established to describe the multi -degree-of-freedom ( MDOF) motion of a ship in space.Based on the instantaneous equivalent motion system , an MDOF coupled motion equation that considers the transient position of the onboard coordinate system is established.The heading control condition is in-troduced and the MDOF motion equation is improved to study the forced-parametrically excited rolling of ships un-der directional navigation in regular oblique waves.The movement of a C11 container ship in a regular oblique wave and different wave conditions is analyzed , which reveals that there is a relatively fixed time delay of phase in the motion with a wavelet angle difference.The influences of the parametric excitation and strong excitation on the mo-tion are related to the wave direction angle , wave amplitude, and wavelength, and these wave conditions also deter-mine if the natural frequency influences the motion frequency when the forced-parametric excitation occurs.关键词
