摘　　要：针对方尾水面舰船,采用Holtrop阻力计算公式,以总阻力为目标函数,据遗传算法,对主要的船型参数进行了优化计算,进而得出了在一系列速度下主要船型参数的最优解及相应的由Holtrop公式计算得到的总阻力,并绘制了在各最优解下由Holtrop公式计算的总阻力随速度的变化曲线,结合Holtrop公式相应图谱对所得优化计算结果进行了分析。结果表明,该方法对于水面舰船的主尺度比等船型参数优选具有较强的实用性。The genetic algorithm was used to optimize the calculation of the hull parameters of the surface warship by taking the total resistance as the target function based on the Holtrop formula,and the solutions of the main hull parameters were obtained for ship sailing at different speeds and the corresponding total resistance calculated by Holtrop formula.The total resistance obtained by Holtrop formula was plotted as a curve changing with speed.According to the charts from Holtrop formula,the result of optimized calculations was analyzed.It shows that the method is applicable to optimiza-ting the hull parameters such as the ship′s main dimension ratios and shape coefficients.
