solidworks波浪能浮标发电装置的设计

摘要近年来，石化类不可再生资源日益短缺，为了解决这一难题，海洋能源的技术开发应运而生。海洋中蕴藏着巨大的能量储备，波浪能具有可再生，密度大的优点。

本文首先分析了国内外波浪能的利用现状和问题，提出了波浪能浮标发电装置的设计。之后介绍了波浪能浮标发电装置的工作原理和液压系统组成，根据微幅波理论得出了水质的运动场，能量场，压强场，并得到数学表达式；通过将压力公式代入弗汝德—克雷洛夫假定法得出了垂直圆柱筒浮子所受的垂直波浪力，得到了浮子起伏位移的式子。86633

然后根据所选择的海况，先对系统的发电机进行了选型，之后对液压马达、液压缸、蓄能器和液压阀进行了计算选型，并确定了浮子的具体尺寸，还计算了装置的能量吸收率。

最后将装置定于渤海海域的全年海况下工作进行了分析与优化，并分析了波浪周期对系统的影响，还用solidworks做出了装置的三维图形。

Abstract In recent years, in order to solve the problem of petrochemical non-renewable resou-rces increasingly scarce, ocean energy technology development came into being。 There are huge reserves of energy in the ocean, the wave energy has the advantage of renewable and density。

In this paper, the current situation and problems of wave energy utilization at home and abroad are analyzed, the design of wave energy buoy generator is proposed。Then it introduces the working principle and the hydraulic system of the wave energy buoy, according to the micro wave theory, the water quality of the sports field, energy field, pressure field and the trajectory of the pressure field are obtained and get the mathematical expression。By Froude - Krylov method to get the vertical cylindrical tube- float suffered vertical wave forces, after obtaining the displacement of the float downs formula。

Then according to the selected sea, the generator of the system is selected。 After the hydraulic motor, hydraulic cylinder, accumulator and hydraulic valve were calculated and type selection, and determine the specific size of the float, the energy absorption rate of the device is also calculated。

Finally，the device is scheduled for the Bohai sea waters of the annual work carried out analysis and optimization, the influence of wave period on the system is also analyzed, and used Solid-works to make the device of three-dimensional graphics。

Key word: Wave energy; Wave energy buoy power generation device; Hydraulic system; Froude-Krylov theory
