摘要

波浪能滑翔器作为近年来一种利用海洋能的创新型设备,在民用和军事方面都有着重要的研究意义和应用价值.本文应用船体设计领域特有的CAD-CFD集成平台Friendship软件,通过其Feature二次开发功能,研究了波浪能滑翔器母船曲面的全参数化建模方法.并以此为基础,采用Sobol优化算法,对母型船进行了多方案优化计算,并对影响阻力的关键参数进行分析,同时对艇体的重心位置和挂点位置的范围做了初步分析.通过优化设计,波浪能滑翔器母船的快速性能得到显著提升,STAR-CCM+的计算结果也佐证了优化的有效性.该方法为波浪能滑翔器母船的快速设计提供了有效途径.%Wave glider is an innovative equipment in recent years, which uses ocean energy as its power. It has signific-ant value in research and application in both civil and military aspects. In this paper, the CAD-CFD integration platform Friendship Framework is used, which is unique in the field of ship design. By using its secondary development function Fea-ture, the parametric modeling method of the surface boat of wave glider is researched. On this basis, the Sobol optimization algorithm helps in the optimization calculation on multiple plans and the analysis on the important parameter affecting the resistance. At the same time, a preliminary analysis on the range of location of gravity and suspension point is made. Through the optimization design, the surface boat's speed and resistance is significantly improved, and the optimization pro-cess is proved valid by STAR-CCM+. This method provides a useful way to the quick design on the surface boat of wave glider.
