摘　　要：使用FAST构建10 MW漂浮式风电机组的完全耦合非线性模型,针对极端情况,通过耦合求解器FAST对张力腿平台(TLP)式风电机组的叶片、塔架和平台等关键部件进行研究。结果表明:在最大运行工况下,TLP式风电机组风轮叶片承受更大的载荷,但在极端停机工况下,塔架承受更大的弯矩和剪切力;TLP在极端停机工况下的响应更剧烈。风轮叶片的结构校核应基于运行工况,而其他部件的结构校核要考虑极端停机工况。FAST is used to construct a fully coupled nonlinear model for the simulation of 10 MW floating wind turbines.For the extreme case,the key components of TLP wind turbines,such as blade,tower and platform,were studied by coupled solver FAST. The results show that under the maximum operating condition,TLP wind turbine’s blade are subjected to greater loads,but under the extreme shutdown condition,the tower bear greater bending moment and shearing force. The response of TLP are more severe under extreme shutdown condition. The structural check of the wind turbine’s blade should be based on operating condition,while the structural checks of other components should consider extreme shutdown conditions.
