Abstract: 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 twin-skeg 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.

Key words: twin skeg, wake objective function, parametric modeling, multi-objective optimization

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。
