摘要
以美国可再生能源实验室(NREL)公布的"5 MW baseline"浮式风力机模型为设计依据,利用设计波的谱分析法,挑选基础结构典型剖面载荷,并对其进行长期预报,计算半潜基础典型受力工况下的设计波要素,结合浮式风力机所受风载荷及6个自由度风力机气动载荷,选择风浪同向为最不利工况,对设计波条件下的结构总体强度进行计算校核。结果表明:结构在2种典型作业工况下强度均满足设计要求。
In this paper,American National Renewable Energy Laboratory(NREL)offshore published 5 MW baseline wind turbine is chosen as design reference. Using the design wave spectrum analysis,select the typical load profiles of infrastructure,and then carry on the long-term forecast to calculate the design wave elements of the semi-submersible foundation under typical force conditions. Combine with the wind load of structure and the six degrees of freedom of wind turbine load,choose wind and waves in the same direction as the most unfavorable conditions. Check the overall structural strength under design wave conditions, the results showed that the structural strength satisfies the requirements.
