本文研究了SPAR型海上浮式风力机在波浪载荷作用下的运动。提出的FOWT样机安装了一台2 MW的顺风型风力发电机组，其转子直径为80m，轮毂高度为55m。梁式浮基吃水60m，下部直径12m，中(主)部直径8.4m，上部直径4.8m。FoWT将由传统的锚链系统系泊。为了设计这样的FOWT系统，预报FOWT在不规则波、湍风、流等环境载荷作用下的运动是必不可少的。本文研究了FOWT在规则波和不规则波作用下的运动，以及与定常风相对应的定常水平力的作用。波槽试验是在国家海洋研究所深海波浪水池中进行的，采用的是FOWT原型的1/22.5比例尺模型。将实验结果与数值模拟结果进行比较，验证了模拟方法的有效性。版权所有：ASME版权所有
In this paper, motion of a SPAR-type floating offshore wind turbine (FOWT) subjected to wave loadings is examined. The proposed prototype FOWT mounts a 2MW wind turbine of down-wind type, whose rotor diameter is 80m and hub-height 55m. The SPAR-type floating foundation measures 60m in draft, having circular sections whose diameter is 12m at the lower part, 8.4m at the middle (main) part and 4.8m at the upper part. The FOWT is to be moored by a conventional anchor-chain system. In order to design such a FOWT system, it is essential to predict the motion of the FOWT subjected to environmental loadings such as irregular waves, turbulent winds, currents, etc. In this paper, the motion of the FOWT subjected to regular and irregular waves is examined together with the application of steady horizontal force corresponding to steady wind. The wave-tank experiment is made in the deep sea wave-basin at NMRI (National Maritime Research Institute), using a 1/22.5 scale model of the prototype FOWT. The experimental results are compared with the numerical simulation results for validation of the simulation method.Copyright © 2009 by ASME
