摘要无人水面艇(unmanned surface vessel,简称 USV),是一种无人操控的水 面舰艇。其作用主要用于执行危险任务以及不适于有人船只执行的任务。无人艇 一旦配备先进的控制系统、通信系统、传感器系统和武器系统后,可以执行多种 战争和非战争军事任务,比如:搜索、侦察、探测和排雷;搜救、导航和水文地 理勘察;反潜作战、反特种作战以及巡逻、反恐攻击等。所以对于 USV 的优化 设计变得十分重要,也是很关键的要求。77331
在研究水面无人艇水动力性能时,通常使用船模试验来进行研究,但由于各 种比如精度,时间,实验环境,资金等很多因素,现实的试验研究并不容易。但 是通过 CFD 方法,可以科学真实地模拟船舶的运动情况,避免了试验的局限性。 本文使用 Fine Marine 进行数值模拟,来研究新型无人艇的水动力性能,并进行 了具有防飞溅条的翼滑艇的阻力分析。

Abstract Unmanned Surface Vessel (Referred to as USV) Is a kind of unmanned surface vessels。 Its role is mainly used to perform dangerous tasks and is not suitable for the task of carrying vessel。 USV once equipped with the advanced control system,communication system, sensor system and weapon systems, can perform a variety of war and non war military operations, such as: search, reconnaissance, detection and mine clearance; search and rescue, navigation and hydro graphic survey;antisubmarine warfare, counter special operations and patrol, terrorist attacks。 So for the optimization of USV design becomes very important, is also a very important requirement。
In the research of unmanned surface vehicle hydrodynamic performance, usually use the ship model experiment to study, but due to a lot of all such as precision, time, experimental environment, capital and other factors, experimental study on practical is not easy。 But through the CFD method, we can simulate the movement of the ship scientifically and avoid the limitation of the experiment。 In this paper, the numerical simulation of Fine Marine series software is used to study the hydrodynamic performance of the new type of unmanned craft, and the resistance analysis of the wing sliding boat with anti splash is carried out。
According to some real ship data and experience formula, through theoretical analysis, model of USV navigation performance comprehensive optimization mathematical model is established, and and discusses the integrated optimization design of a novel monomer USV sailing performance。
Taking into account the USV speed, maneuverability and sea keeping, established a comprehensive optimization mathematical model of the new USV navigation performance。 Choose genetic algorithm, particle swarm optimization algorithm, hybrid algorithm and chaos algorithm four algorithms as the basis of the optimization calculation of this paper, and based on the new USV based C# integrated navigation performance optimization procedures。 According to adapt good comprehensive optimization program, completed the a lot of optimization calculation,
