摘　　要：将参数化建模技术与CFD仿真技术相结合,并进行阻力性能优化是目前最常用的船型优化方法。该文以某双艉鳍集装箱船为研究对象,为提高航行性能,对其双艉鳍进行设计优化。采用全参数化建模方法对双艉鳍进行参数化设计,同时,通过CFD仿真技术、结合NSGA-Ⅱ优化算法并以阻力及伴流均匀度为优化目标,完成双艉鳍船型的优化设计。优化后的船型在阻力降低的基础上,伴流均匀度也获得明显改善。Combing the parametric modeling technology with the CFD simulation technology to optimize resistance is currently the most commonly used ship optimization method.The optimization design of the twinskeg is carried out for a twin-skeg container ship to improve its navigation performance.The full parametric modeling method is used to carry out the parametric design of the twin-skeg.And the CFD simulation technology and the NSGA-Ⅱ optimization algorithm are adopted to conduct the optimization design of the twin-skeg with the optimization objectives of resistance and wake uniformity.The resistance of the optimized ship form is reduced with the significant improvement of wake uniformity.
