摘要
基于CFD的船型优化已是国内外的研究热点,但鲜有学者研究优化参数的数量对优化结果的影响.文中利用船型优化平台,以KCS船模的兴波阻力系数为优化目标,研究船型优化过程中优化参数的数量对船型优化结果的影响.研究结果表明,适当增加优化参数的数量能够扩大优化空间,从而获得潜在的性能更优的船型设计方案.
CFD-based ship form optimization has become a hot research topic at home and abroad,but few scholars have studied the influence of the number of optimization parameters on the optimization results.In this paper,using the ship type optimization platform independently developed by the research group and taking the wave-making resistance coefficient of KCS ship model as the optimization objective,the influence of the number of optimization parameters on the ship type optimization results in the process of ship type optimization was studied.The results show that an appropriate increase in the number of optimization parameters can enlarge the optimization space,thus obtaining a potential ship type design scheme with better performance.
