| 摘要海洋是一个巨大的能量库，其中波浪能更具有可再生、对环境破坏小、污染少等诸多优点，海浪发电研究具有广阔的发展空间。而基于液压系统的浮子海浪发电系统不破坏海岸、海底，投入使用可大量生产，易统一标准，现有技术成熟等突出特性。33252 文中对海浪发电的国内外研究现状及历史做了回顾，也对未来海浪发电发展趋势进行了预测，选取国内外几个典型的海浪发电装置，并对其工作原理和特点做了分析，总结各装置的优缺点，提出了本课题的研究内容。 对实际海域的各参数了解后设计一种海浪发电系统并选择主要元件，首先根据弗汝德一克雷洛夫假定法计算不同形状的浮标如垂直圆柱体、长方体和球体所受的垂直波浪力以及在海浪力作用下的行程，最后确定浮体形状。在研究和得出浮子各项参数后设计出海浪液压系统。根据受力和运动幅度等，分析负载后，设计液压缸的结构类型和具体尺寸，最后对液压缸进行校核。已知流量、压力等信息后，再根据海浪发电发电波动大，工作的环境恶劣，选择合适的液压马达，并匹配对应的电动机。由于海浪发电的特性，蓄能器的选择尤为重要。所以本案系统考虑工作温度，压力变化幅度，详细计算蓄能器的调节能力，最终确定稳定油压，且变化周期较快，响应时间较短的气囊式蓄能器。最后对系统中其他元件进行选择。 [毕业论文关键字]：波浪能、浮标式、液压系统、发电、F-K假定法 Abstract Ocean is a huge energy library, in which the wave energy is renewable, damage to environment is small, less pollution, and many other advantages, the waves power generation research has broad space for development. And float the waves power generation system based on the hydraulic system does not destroy the coast, the bottom of the sea, in use can be mass production, unified standards, the existing mature technology such as prominent features. Of the waves of the domestic and foreign research present situation and history do to review, and the waves power generation for the future development trend is forecasted, select several typical wave power devices at home and abroad, and has made the analysis of its working principle and characteristics, summarizes the advantages and disadvantages of each device, puts forward the research content of this project. To understand the parameters of the actual area after the design of a wave power generation system and choosing the main components, first of all, according to Mr RuDe a buoy in the shape of krylov assumption method to calculate different vertical cylinder, such as cuboid and sphere of vertical wave force and under the action of wave force, finally determine the floating body shape. After the study and to obtain all parameters of the float design waves hydraulic system. According to the force and movement range, etc., after analysis of the load, design the structure of the hydraulic cylinder type and size, the final check on the hydraulic cylinder. Known the information such as flow, pressure, and then according to the wave power generating volatility, bad work environment, choosing the appropriate hydraulic motor, and match the corresponding motor. Due to the nature of the wave power generation, the choice of the accumulator is particularly important. So this case system considering working temperature, pressure change, the detailed calculation of the accumulator regulating ability, eventually determine the stable oil pressure, and the cycle is changing fast, short response time of air accumulator. Finally, choose other components in the system. Key words: wave energy, buoy type, hydraulic system, power generation, f-k assumption method 目 录 摘 要 I (责任编辑：qin) |
