Abstract: In order to research the dynamic response of offshore wind turbines under different seismic impact angles,a soil-structure interaction model was constructed based on the p-y curve method,and a finite element model was established with DTU 10 MW monopile offshore wind turbine as the research object to study the impact of seismic impact angle changes on the seismic dynamic response of large offshore wind turbines. The results show that the seismic impact angles of 0° and 90° are the most violent angles of the wind turbine structure under load response. When the seismic impact angle is acute,the front-to-back and lateral displacement amplitude of the tower top decreases and the total strain energy accumulation is significantly alleviated. When the seismic impact angle is 15° and 30°,the equivalent stress of wind turbine decreases obviously compared with other angles. Therefore,actively adjusting the orientation of wind turbine wheels to adjust the seismic impact angle may be an effective control method to reduce the damage of wind turbines after being impacted by earthquakes.
