| Abstract: | The support structure composed of the pile foundation, tower and connecting components of a wind turbine is a mechanical structure that bears a large mass on top, and the impact of earthquakes on it is much greater than that on a conventional building. To address these issues, the dynamic response of wind turbines under variable wind and seismic loads （waveform and intensity） was investigated based on the NREL development computational platform, in conjunction with TurbSim, AeroDyn, FAST and Seismic. It is found that： the seismic transverse waves have a drastic effect on the structural response of the wind turbine, while the longitudinal waves have less effect compared to the transverse waves; the structural response of the wind turbine is more drastic in the horizontal direction than that in the vertical direction, while the structural response in the vertical direction is negligible in the structural analysis. The structural response of the blades is mainly caused by wind loads; due to the action of wind loads in the incoming direction, the tower top flow displacement and tower frame lateral bending moment are affected by both wind and seismic loads, and the tower top lateral displacement and tower frame flow bending moment are more significantly affected by seismic loads. |
