摘 要 全球范围内大规模开发、利用、争夺海洋资源，海上权益之争愈演愈烈。在这样的大背景下，水面无人艇受到了各海上强国的高度重视。水面无人艇作为一种新概念船，它可以广泛执行巡逻、侦察、监视、反恐攻击等危险任务。世界各国都在积极进行无人艇的设计研发工作。 本文主要研究的对象是一艘小水线面双体船。小水线面双体船兼具了潜艇、双体船的许多的优点，具有甲板面积大、稳定性好、航行性能优良等许多优点，是现在综合性能优秀的船型。因此，我选用小水线面双体船作为这艘无人艇的船型。 首先，进行的是船舶数学模型的建立。船舶的设计是一个多变量，多目标，多约束条件的复杂过程。因此，我只从船舶的快速性、操纵性、耐波性、太阳能能量输出综合四个方面入手，进行设计变量的选择，目标函数的构造，约束条件的确定。 其次，使用小水线面双体船的简化型线确定这艘船的主要参数，用cad 建立小水线面双体船的实体计算模型，然后进行网格的划分，接着在FINE/Marine 里进行的数值模拟计算。从以上阻力计算结果可知：小水线面双体船的阻力较同船长的其他船舶要小很多；小水线面双体船的片体瘦长，阻力随吃水的变化较小；小水线面双体船在高速时显现出很高的优越性。 然后，通过综合比较分析最终确定使用粒子群算法进行优化计算，并确定最优船型。 58504

Abstract Large scale development, utilization and contention of marine resources in the global scope, the maritime rights and interests of the dispute intensified. In such a large background, the USV is highly valued by a large country. As a new concept ship, USV has a wide range of tasks such as patrol, reconnaissance, surveillance, anti terrorist attack and so on. Countries around the world are actively working on the design and development of USV. This paper focuses on the research of a SWATH ship. SWATH has many advantages of submarine and catamaran and has a large deck area, good stability, excellent navigation performance, being an excellent ship form. Therefore, we choose the SWATH as the ship form. First of all, the mathematical model of the ship is established. Ship design is a multi variable, multi objective and multi constraint condition. Therefore, I only from ships rapidity, manipulation, seakeeping, output of the solar energy comprehensive four aspects analysis the choice of design variables, objective function, the constraint conditions. Secondly, I design the main parameters of the ship and draw simplified lines. using CAD to establish swath entity geometric model, then carring on the grid pision and the numerical simulation and calculation in FINE/Marine are my next steps. From resistance calculation results show that: the resistance of swath is less than other ships; swath of slender body resistance changes little with the increase of the draft; swath at high speed showing very high priority. Then, I use the particle swarm optimization algorithm to optimize the calculation, and determine the optimal ship type.
