摘　　要：为提高船体的优化效率,以国际标准船型KCS为研究对象,以船舶总阻力和桨盘面伴流不均匀度为优化目标,建立近似模型,完成KCS船尾线型的优化,得到优化船型.通过优化结果可知:对于母型船,在满足工程约束条件下,通过船尾优化可以得到总阻力未增加、船尾流场品质有明显改善的船体线型.To improve the optimization efficiency of ship hull, the international standard ship type KCS is taken as the research object. The total resistance and the wave non-uniformity at the propeller disk are taken as the optimization goals, an approximation model is built, and the KCS stern line is optimized. The optimization results indicate that, under the engineering constraint conditions, the optimization on the stern of original ship can obtain an improved ship hull line, of which the total resistance is not increased and the stern flow field quality is significantly improved.
