为了获得可再生能源，迫切需要开发一种性价比高的浮动式风力发电系统。本文对采用钢筋混凝土的梁式浮式基础进行了研究。对样机进行了1/100比例尺的规则波和不规则波试验。考察了三种模型，即在重心处系泊的均匀圆柱体、在上部系泊的均匀圆柱体和在上部系泊的阶梯式浮动圆柱体。实验结果与用势理论和Morison方程进行数值预测的结果进行了比较。停泊在上部的阶梯式浮筒比均匀浮筒运动小。
It is strongly desired to develop a cost-effective wind turbine system of floating-type in order to gain the renewable energy resources. In this study, the SPAR-type floating foundations using reinforced concrete are examined. The regular and irregular wave experiments are performed for 1/100 scale models of the prototypes. Three models are examined, that is, a uniform cylinder moored at the gravity center, a uniform cylinder moored at the upper position and a stepped-type floating cylinder moored at the upper position. The experimental results are compared with numerical predictions using potential theory and Morison’s equation. The stepped-type floating cylinder moored at the upper position has shown smaller motions than the uniform cylinders.
