Abstract

Most of the wind turbine towers in my country are inevitably built in earthquake-prone areas, which are prone to dynamic buckling under the wind-earthquake coupling because they are thin-walled structures. Therefore, a 2.5 MW wind turbine in Northwest China was taken as a prototype to study the dynamic buckling of wind turbine tower under the coupling effect of wind and earthquake. First, the harmonic superposition method, the blade element momentum theory and the wake model were used to calculate the wind load on the wind turbine tower under operating conditions. Secondly, the finite element model of the wind turbine tower was established, and the influence of different loading angles on the dynamic response of the wind turbine tower under the wind, earthquake and wind-earthquake coupling was discussed. Finally, combined with the incremental dynamic analysis, a method based on the phase diagram method of the most unfavorable tower top displacement was proposed to study the dynamic buckling of the wind turbine tower under the wind-earthquake coupling, and its dominant factors were discussed. The results show that the effect of wind-earthquake coupling will lead to additional demands on the strength of the wind turbine tower. In determining the orientation of the door opening, the factors of wind-earthquake coupling should be considered. The wind turbine tower exhibits local plastic dynamic buckling under the wind-earthquake coupling, and the "phase diagram method of the most unfavorable tower top displacement" can accurately identify and analyze the dynamic buckling of the wind turbine tower.
