风浪作用下的Spar型海上垂直轴风机运动响应
摘要
能源问题已经成为了国内外关注的重点，而风能作为一种永久性的清洁的能源，成为了国内外学者的研究对象。为进一步地开发海上的风力资源，现大多数国家已将靠岸的风电场推向更远的海域或深海，从经济上看在海面上要求使用浮动支撑结构是可持续的。所以本文以风能作为变量，以海面作为生态环境，以风机作为研究对象来展开的研究。
本文某一风机为基础设计了Spar型海上垂直轴风机，通过对Spar型海上垂直轴风机的研究进行了方案的设计，并且进行了相关参数的优化，利用相关的软件进行了模型的设计和建模。传统水平轴风力发电机的简明比较并简要介绍了这些技术的优缺点。最后对此进行详细的研究和处理。
通过对于Spar型海上垂直轴风机的研究所得到的结果显示载荷对于Spar型垂直轴浮式风力发电机的纵荡、纵摇响应影响较大，对垂荡影响较小；波浪载荷对各自由度的运动响应均有较大影响。

Motion response of Spar vertical shaft fan under wind and wave action
Abstract
Energy problem has become the focus of attention at home and abroad, and wind energy as a kind of permanent clean energy, has become the research object of domestic and foreign scholars. In order to further develop the offshore wind resources, most countries have pushed the landing wind farm to the farther sea area or the deep sea. From the economic point of view, it is sustainable to use floating support structure on the sea surface. So this paper takes wind energy as variable, sea level as ecological environment and fan as research object. On the basis of a certain fan, this paper designs Spar type marine vertical shaft fan. Through the research of Spar type marine vertical shaft fan, the scheme is designed, and the related parameters are optimized. The model is designed and modeled by using related software. The advantages and disadvantages of the traditional horizontal axis wind turbine are briefly introduced. Finally, the detailed research and treatment are carried out. The results obtained from the study of Spar type offshore vertical shaft fan show that the load has a great influence on the vertical swing response of the Spar vertical axis floating wind turbine, but has little effect on the heave. The wave load has great influence on the motion response of each degree of freedom.
Key words: wind and wave; spar,;vertical axis; fan, motion response
