摘要：
Different from onshore wind turbines, offshore wind turbines are subjected to wind loads and hydrodynamic loads, which caused by sea waves. The mechanical load characteristics of foundation structure and main components of offshore wind turbine are more complicated due to the coupling of wind and wave loads. To ensure the safety of the operational structure of offshore wind turbines, the influence of wave conditions on the load characteristics of offshore wind turbine main components should be taken seriously. Based on the improved JONSWAP spectrum, a wave dynamics model is established, and the effects of the wave on the ultimate and fatigue load characteristics of offshore wind turbine are simulated, taking the blade flapwise and tower base tilt bending moments as examples. Finally, based on the measured and simulated mechanical load data of offshore wind turbine, the wave dynamics model was verified. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
