1、船舶与海洋工程毕业论文船舶与海洋工程毕业论文高速无人艇设计与运动性能初步分析专业船舶与海洋工程I船舶与海洋工程毕业论文摘要高速无人滑行艇具有高速、隐身、智能等优点,因而能够用于灵活作战,目前,国外已有多种水面高速无人艇应用于军事领域,特别是以美国为代表的西方国家已将其列为重要的发展方向;国内在水面高速无人艇技术方面的研究还处在初级阶段,近年来研制出的无人驾驶船也只是应用于探测天气,为了更好低完善我国海军作战体系,带动相关军工业的发展。本文进行的主要工作有:一、针对目前国内外的高速无人艇研究发展现状展开了调查研究,并对
2、我国目前滑行艇阻力、稳性、耐波性和新艇型的开发进行简单的介绍。二、从任务需求出发,结合现有条件,利用Maxsurf软件进行单体滑行艇模型的设计,并对模型进行了流体性能的初步计算分析。三、进行了推进器的设计,并对喷水推进器的种种要素对各个性能的影响进行了分析。四、以滑行艇前进、升沉及纵摇运动为目标开展滑行艇流体性能的初步分析。五、建立了船前进、升沉、纵摇三自由度运动数学模型,开展了滑行艇三自由度运动预报,分析了高速滑行艇运动特点。关键词:无人滑行艇性能分析三自由度运动数学模型运动预报II船舶与海洋工程毕业论文Abstr
