摘　　要：目前国际海事组织(IMO)已初步完成了参数横摇薄弱性衡准的制定工作.为研究艏艉型线对参数横摇薄弱性的影响,选取实际航行中发生过参数横摇的C11集装箱船作为母型船,应用调整B样条曲面控制点的方法,通过改变母型船艏部外飘程度和艉框轮廓线升高高度,生成2个系列共8艘新船型,并对系列船型应用前期开发的参数横摇薄弱性校核程序进行参数横摇薄弱性计算,计算结果表明:船艏外飘程度增加或艉框轮廓线升高高度降低,将导致船舶在波浪中初稳性高变化幅值逐渐减小,船舶不容易发生参数横摇.At present,the International Maritime Organization(IMO)has preliminarily completed the formulation of the parameter rolling weakness criterion.In order to study the influence of stem and stern contours on the weakness of parametric rolling,C11 container ship which has experienced parametric rolling in actual navigation was selected as the mother ship.By adjusting the control points of B-spline surface,eight new ship types in two series were generated by changing the outward floating degree of bow and the rising height of stern frame contour.In addition,the parametric roll weakness checking program developed in the early stage of the application of series ship types was used to calculate the parametric roll weakness.The calculation results show that the increase of bow floating degree or the increase of stern frame contour line and the decrease of height will lead to the gradual decrease of the change amplitude of the high initial stability of the ship in waves,and the ship is not prone to parametric rolling.
