【摘要】：海洋波浪能作为一种取之不尽用之不竭的无污染可再生能源，很多国家加大了对海洋波浪能的开发和研究力度，而且取得了一些成果，但波浪能的开发仍面临着很多问题，振荡浮子式波浪能发电装置作为一种波浪能捕获的有效装置，，也存在诸多亟待解决的问题，如针对不同的波高参数对应的振荡浮子形状尺寸优化，同时振荡浮子容易受到大波浪的损坏、效率低等。本文针对振荡浮子式波浪能发电装置以上面临的问题做出了实验分析。 首先，本文提出了相对运动式波浪能发电测试装置，并对实验装置进行了设计与搭建，包括实验平台、往复运动控制系统、数据采集系统等。其次，为提高振荡浮子的能量捕获效率，本文建立了浮子的运动轨迹模型和能量捕获效率模型，在此基础上，设计了浮子放置方式、浮子吃水深度等参数，针对其对浮子能量捕获效率和功率的影响进行了实验测试；为提高振荡浮子的可靠性，本文提出了初步的仿生浮子试验，实验中提出了三种仿生浮子：柔性浮子、类水母浮子、类海藻浮子，并将这三种浮子和水平圆柱浮子做了对比实验分析，测试了其对浮子能量捕获效率和抗浪性能的影响。通过对上述实验测试的分析，为波浪能发电装置大型实物样机浮子的设计提供了设计依据。
[Abstract]:Ocean wave energy as an inexhaustible non-polluting renewable energy, many countries have increased the development and research of ocean wave energy, and achieved some results, but the development of wave energy is still facing a lot of problems. As an effective device for wave energy capture, there are many problems to be solved, such as optimizing the shape and size of oscillating floats corresponding to different wave height parameters. At the same time, the oscillating float is easy to be damaged by large waves and low efficiency. In this paper, the above problems of oscillating float wave energy generator are analyzed experimentally. First of all, this paper presents a relative moving wave energy generation test device, and the experimental device is designed and built, including the experimental platform, reciprocating motion control system, data acquisition system and so on. Secondly, in order to improve the energy capture efficiency of the oscillating float, the motion trajectory model and the energy capture efficiency model of the float are established in this paper. In order to improve the reliability of the oscillating float, a preliminary bionic float experiment was proposed, in which three kinds of bionic floats were proposed: flexible float, jellyfish float, and jellyfish float. The effects of the three floats on the energy capture efficiency and the anti-wave performance of the floats were tested and compared with those of the horizontal cylindrical floats. Through the analysis of the above experimental tests, the design basis for the design of a large prototype float for wave energy generating equipment is provided.
