摘要
建立基于Spar平台的5MW漂浮式风力机整机模型,旨在探讨结构的动态响应和所受波浪力以及它们随水深的变化情况。考虑海风、海浪和海流载荷的作用,借助有限元软件对结构进行水动力计算,得到结构的频域特性和位置响应的时间历程,并进一步分析不同水深条件对响应特性的影响。结果表明:水深条件对Spar型漂浮式风力机在外界载荷作用下的动态响应和所受波浪力情况有着显著影响。
The whole machine models for Spar platform supported offshore wind turbines were built to re-search the dynamic response and wave force components and their variation trend with water depth .Hy-drodynamic calculations were carried out considering wind , wave and current load to obtain the frequency-domain performance and time-domain responses and further the study of researching the impacts of wa-ter depth on the dynamic performance .The results show that dynamic responses of Spar supported off-shore wind turbines are apparently influenced by water depth .
