【摘要】 本研究利用基于Rankine源的面元法开发了船舶与波浪相互作用的时域预报方法,计算中使用线性自由面条件,平均时湿表面面元;利用数值阻尼法来满足辐射条件。并对2条船进行了顶浪状态的运动响应预报,通过与试验值比较,验证本研究数值方法合理、可靠。更多还原

【Abstract】 A time domain prediction of ship and wave interaction based on Ranine panel mehtod is investigated 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 conditons.The motions of two vessels in regular head waves are computed by this method.The present numerical results are compared with the experiment data,.The comparison shows satisfactory agreements for the RAOs of pitch and heave.更多还原
