摘　　要：采用一种势流兴波数值优化方法与RANS求解器的优化结合的方法对某中速船的首部进行线型优化,以便使其速度达到设计要求。经过多轮数值优化试验,取得一个优化方案。最终的优化方案经模型试验验证,总阻力下降约2.7%,预报航速提高约0.4kn。A potential wave-making numerical method in combination with the RANS solver is used to optimize the forward part line of a middlespeed ship in this paper, so that the design speed Of the ship meets the predetermine speed. The model test of the optimized hull is carried out, the results show the speed could be increased about 0.4kn compared with that before optimization, so this speed satisfies the design reguirement.
