| 中文摘要: |
| 风力机发展趋势使深海漂浮式风力机有着广阔发展前景.分析了漂浮式多浮柱平台的稳定机理,根据美国可再生能源实验室5 MW风力机模型,提出了平面对称结构浮柱平台设计思路,同时初步建立了深海多浮柱平台三维有限元模型.结合机械振动理论,采用有限元计算软件对三浮柱、四浮柱以及六浮柱平台模型进行模态分析,为进一步开展漂浮式平台的优化设计提供了一定参考依据. |

| With the rapid development of wind power utilization, deep sea floating wind turbines will have a promising future.In this paper, different kinds of ocean floating structures were compared in order to find the appropriate platform for floating wind turbines.Based on the 5 MW wind turbine model that presented by the U.S.National Renewable Energy Laboratory (NREL), design ideas for multi-floater platforms were proposed and analyzed.Combining the theory of mechanical vibration, the model analysis of the designed platforms was carried out using the finite element simulation software, which provides a reference to optimum design of floating platforms. |
