摘　　要：文章着眼于球鼻艏设计,提出一种球鼻艏几何形状的插值表达方法,把球鼻艏的设计参数减少至5个,提出采用多岛遗传算法数值优化兴波阻力的球鼻艏设计方法。最后,对KCS船的球鼻艏进行了优化设计,结果显示,其兴波阻力较原方案降低了10%,初步验证了该设计方法的有效性。Focusing on the bulbous bow design, the paper develops an interpolation method for the bulbous bow geometry, which reduces design parameters of bulbous bow to five. A new design method for bulbous bow is proposed by using multi-island genetic algorithm for lines optimization of the bulbous bow with lowest wave-making resistance. Finally, an optimization design for the bulbous bow for KCS is performed. The result shows a further reduction of wave-making resistance by 10%, which shows that preliminarily the current method is efficient.
