【摘要】：海洋波浪能作為一種取之不盡用之不竭的無(wú)污染可再生能源，很多國(guó)家加大了對(duì)海洋波浪能的開(kāi)發(fā)和研究力度，而且取得了一些成果，但波浪能的開(kāi)發(fā)仍面臨著很多問(wèn)題，振蕩浮子式波浪能發(fā)電裝置作為一種波浪能捕獲的有效裝置，，也存在諸多亟待解決的問(wèn)題，如針對(duì)不同的波高參數(shù)對(duì)應(yīng)的振蕩浮子形狀尺寸優(yōu)化，同時(shí)振蕩浮子容易受到大波浪的損壞、效率低等。本文針對(duì)振蕩浮子式波浪能發(fā)電裝置以上面臨的問(wèn)題做出了實(shí)驗(yàn)分析。 首先，本文提出了相對(duì)運(yùn)動(dòng)式波浪能發(fā)電測(cè)試裝置，并對(duì)實(shí)驗(yàn)裝置進(jìn)行了設(shè)計(jì)與搭建，包括實(shí)驗(yàn)平臺(tái)、往復(fù)運(yùn)動(dòng)控制系統(tǒng)、數(shù)據(jù)采集系統(tǒng)等。其次，為提高振蕩浮子的能量捕獲效率，本文建立了浮子的運(yùn)動(dòng)軌跡模型和能量捕獲效率模型，在此基礎(chǔ)上，設(shè)計(jì)了浮子放置方式、浮子吃水深度等參數(shù)，針對(duì)其對(duì)浮子能量捕獲效率和功率的影響進(jìn)行了實(shí)驗(yàn)測(cè)試；為提高振蕩浮子的可靠性，本文提出了初步的仿生浮子試驗(yàn)，實(shí)驗(yàn)中提出了三種仿生浮子：柔性浮子、類水母浮子、類海藻浮子，并將這三種浮子和水平圓柱浮子做了對(duì)比實(shí)驗(yàn)分析，測(cè)試了其對(duì)浮子能量捕獲效率和抗浪性能的影響。通過(guò)對(duì)上述實(shí)驗(yàn)測(cè)試的分析，為波浪能發(fā)電裝置大型實(shí)物樣機(jī)浮子的設(shè)計(jì)提供了設(shè)計(jì)依據(jù)。
[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.
