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。 关键词：风浪；spar型；垂直轴；风机；运动响应 Motio
