摘　　要：采用分层次优化,首先以总阻力最小为优化目标对某三体船侧体横向和纵向的相对位置进行了优化研究,得到阻力性能最优的三体船侧体布局方案;然后基于侧体最优布局,进行型线优化,最终完成三体船的侧体布局和型线的序列优化。结果表明,所采用的三体船侧体布局及型线优化方法具有可行性,可为三体船船型设计提供参考依据。Adopting the hierarchical optimization, the paper firstly studies on the optimization design of the relative positions of horizontal and vertical side hull of the trimaran, with the minimum total resistance as the optimization objective. The side hull location scheme of the optimal resistance performance is obtained Then hull line optimization is carried out based on the side hull optimal location. Finally, the optimization of side hull location and hull line of the trimaran are completed The results indicate that the optimization method of the trimaran side hull location and hull line optimization method adopted in the paper is feasible, which can provide reference for trimaran ship type design.
