【摘要】：随着世界范围内化石能源的日益短缺，寻找新型替代能源显得尤为迫切。波浪能作为一种储量丰富的可再生绿色能源，得到了世界各国越来越多的关注和研究，经过多年的技术积累后现已逐步接近实用化水平，特别是在一些缺乏常规能源的海岛和海上设施中，波浪能显示出了其特有的优越性和生命力。本文针对双浮体式振荡浮子波能捕获装置展开了分析和研究，提出了利用陀螺浮子吸收波浪能，并从以下几个方面展开工作。首先，指出了课题的研究背景和意义，综合阐述了国内外波浪能发电的研究现状、存在的问题以及发展的趋势，并介绍了本课题的研究内容。其次，简要介绍了波浪能发电的一般组成和分类，针对其中存在的部分问题，提出了一种以无动力双体船为载体的海上发电试验平台，描述了平台的整体结构组成，重点介绍了双浮体式波浪能发电装置的工作和能量转换原理，接着对发电装置各个组成部分进行了详细的分析，并提出了本系统装置的关键技术问题，为后文的仿真分析打下基础。然后，根据微幅波理论和推进波的势函数推导相关的数学表达式，基于弗汝德－克雷洛夫假定法对常见的浮子进行受力分析并引入了圆锥浮子，提出了由圆柱与圆锥组合而成的陀螺浮子作为装置的捕能机构。为了验证陀螺浮子的合理性，首先建立装置的数学模型，，然后以Workbench为工具，从浮子在波浪冲击下的适应性、功率特性、效率特性三方面入手，对不同形状浮子进行流固耦合分析，得出选择陀螺浮子作为试验平台波浪能捕获机构是非常合理的；紧接着从5个方面对陀螺浮子进行了分析，为陀螺浮子的具体选取提供了一定的依据。最后，先对整个试验平台主要部分的结构设计进行了简要的描述；接着，设计并搭建了相对运动式波浪能捕获实验装置，对理论模型和仿真模型进行了验证，同时，为进一步提高浮子的抗浪适应性，仿生设计了三种柔性结构的浮子模型，并进行了实验测试，得出了结论，为波浪能装置实物样机的研制和即将进行的海试提供了实验依据。
[Abstract]:With the increasing shortage of fossil energy in the world, it is urgent to find new alternative energy. Wave energy, as a kind of renewable green energy with abundant reserves, has been paid more and more attention and research in the world. After years of technological accumulation, it has gradually approached the practical level, especially in island and offshore facilities that lack conventional energy, The wave energy shows its unique superiority and vitality. In this paper, the analysis and research of the double floating oscillating float wave energy capture device are carried out, and the use of the gyro float to absorb the wave energy is put forward, and the work is carried out from the following aspects. Firstly, the background and significance of the research are pointed out, and the research status, existing problems and development trend of wave power generation at home and abroad are comprehensively described, and the research contents of this subject are introduced. Secondly, the general composition and classification of wave power generation are briefly introduced. In view of some problems, an offshore power generation test platform based on unpowered catamaran is proposed, and the overall structure of the platform is described. This paper mainly introduces the work and energy conversion principle of the double floating wave energy generating device, and then analyzes each component of the generating device in detail, and puts forward the key technical problems of the system. It lays a foundation for the simulation analysis of the following article. Then, according to the theory of micro-amplitude wave and the potential function of the propulsion wave, the related mathematical expressions are derived. Based on the Froud-#internal_person0# assumption method, the force of the common float is analyzed and the conical float is introduced. In order to verify the rationality of the gyro float, a mathematical model of the device is first established, and then, with Workbench as a tool, the adaptability of the float under wave impact is studied. Starting with three aspects of power characteristic and efficiency characteristic, the fluid-solid coupling analysis of floats with different shapes is carried out, and it is concluded that it is very reasonable to select gyro float as the wave energy capture mechanism of the test platform. Then the gyro float is analyzed from five aspects, which provides a basis for the selection of gyro float. Finally, the structure design of the main parts of the whole test platform is described briefly. Then, the experimental device of relative moving wave energy capture is designed and built, and the theoretical model and simulation model are verified, at the same time, In order to further improve the anti-wave adaptability of the float, three kinds of flexible structure float models are designed and tested, and the conclusion is drawn, which provides the experimental basis for the development of the physical prototype of the wave energy device and the upcoming sea test.
