中文摘要：

兴波阻力是高速船总阻力的主要成分，对非对称双体船而言，优化侧体布局以降低兴波阻力，是提高其船舶能效的有效手段。论文根据线性兴波理论推导了非对称双体船兴波阻力及兴波干扰因子的计算公式，分析了非对称双体船的兴波阻力特性，研究了侧体的相对位置对兴波阻力的影响规律。基于Isight优化平台，结合线性兴波理论，采用混合遗传算法，以兴波阻力最小为目标，对非对称双体船的侧体布局进行了优化分析。在给定航速下的优化结果相比初始方案的兴波阻力更小，表明本方法可为非对称双体船的侧体布局设计提供参考。

英文摘要：

Wave-making resistance is a main component in total resistance of a high-speed ship. Based on linear wave-making resistance principle, calculation formulas of wave-making resistance and interfering factor for asymmetric catamaran are derived and characteristics of wave-making resistance are analyzed. The effect of piece hull＇s position on wave-making resistance is researched. A hybrid genetic algorithm based on the Isight optimization platform is applied to the optimization of the piece hull＇s position with minimum of wave-making resistance as the goal. The optimization scheme has smaller wave-making resistance than that of the initial one at given speed, which shows that this method can provide a reference for the design of piece hull＇s position for asymmetric catamaran.
