| 摘 要： | 在船舶与波浪相互作用时的三维预报方法的基础上,发展了SPAR平台与规则波相互作用的时域数值预报方法,该方法计入了SPAR平台垂荡和纵摇阻尼效应。使用该方法对一经典SPAR平台进行了规则波中的时域数值模拟。通过计算分析可以看出,该方法能捕捉SPAR平台在临界波浪周期下的耦合运动,验证了该方法的可靠性。

| Abstract: | A time domain prediction of SPAR platform motions based on Rankine panel mehtod is investigated with the interaction between wave and platform taken into consideration in this paper.The linear free surface boundary condition and mean wetted surface are adopted,while the numerical damping method is used for the radiation conditions.Motions of SPAR platform in regular waves are computed with this method. |
