摘要：
To analyze the structural loads at the blade root and tower of a wind turbine, in this study, we used an aerodynamic-hydrodynamic coupled analysis model to simulate the one-degree-of-freedom motion response of an offshore wind turbine in unsteady wind and regular wave conditions. We also compared and analyzed the influences of three longitudinal motions on the structural loads of the blade and tower. The results show that the motion response dramatically increases the structural loads of the wind turbine, Therefore, reducing the structural loads at the blade root and tower should become an important design requirement. This paper reveals the influence of motion on the structural loads of the offshore floating wind turbine and provides direction for optimizing the design of a larger megawatt-level floating wind turbine system. © 2018, Editorial Department of Journal of HEU.
