摘要随着人类对不可再生资源例如石油，矿石，煤等的不断开发和开采，大自然 中所有的资源都在逐渐缩减，人们开始重视可再生资源，如何更高效的利用开发 可再生资源渐渐成为各国可持续发展中不可忽视的内容。我国是一个沿海国家， 海岸线的总长度约有 3。2 万公里之多。在这海洋中有着不可估计的能源资源，风 能就是其中之一，所以建设大批海洋风电平台是未来海洋平台中很重要的一部分。81341

本文以我国 1600T 风电安装平台为研究对象，对风电安装平台在模拟的海 洋环境情况的运动情况进行分析，主要是风电安装平台的水动力性能进行分析。 论文的主要研究内容如下：

首先使用水动力分析工具 AQWA-Line 模块进行风电安装平台的建模，在 时域耦合分析理论、三维势流理论的基础上对风电安装平台模型进行计算分析， 得到辐射阻尼系数、运动幅值响应算子（RAO）、附加质量系数等水动力参数， 分析平台在模拟海洋环境下的运动特性。然后又建立了风电安装平台的时域耦合 计算模型，使用 AQWA-Drift 的模块，模拟了风电平台在真实的海洋大环境中 的运动情况，获得了风电平台不同的自由度的运动响应谱、响应过程，还有系泊 缆在这情况下的受力。

毕业论文关键字：风电安装平台；AQWA；水动力性能；时域耦合分析

Abstract With the human of non renewable resources such as petroleum, ore, development and exploitation of coal, less and less in nature have more resources, renewable resources, more and more attention should be paid to the human, how efficient the development of renewable resources gradually become not to be ignored in sustainable development in all countries。 In this piece of land has not been explored by humans, there is an estimated energy resources, wind energy is one of them, so the construction of a large number of offshore wind power platform is a very important part of the future of the offshore platform。

In this paper, the 1600T wind power installation platform for the study, the wind power installation platform in the simulation of the situation of the movement of the marine environment is analyzed, mainly the wind power installation platform for the analysis of hydrodynamic performance。 The main research contents of this paper are as follows:

Firstly, the hydrodynamic calculation and analysis software AQWA-Line module of wind power installed platform modeling, which is based on the three dimensional potential flow theory, time domain coupled analysis theory on the installation platform model were time domain and frequency domain analysis, get the platform of the added mass coefficient, radiation damping coefficients and motion response amplitude operator (RAO) and other hydrodynamic parameters, analysis of the movement characteristics of the platform in a simulated marine environment。 Then established the wind power installation platform of the time-domain coupled numerical model, the module AQWA-Drift, movement platform in the real ocean environment was simulated, the platform for each degree of freedom of motion response time history and response spectrum, and mooring line force situation。

Keywords: wind power installed plat; AQWA;  Hydrodynamic   performance;

Coupled analysis in time domain
