摘要：

Aiming at the problem of the first-order vortex induced vibration of the steel tower of the wind turbine generator system （WTGS），the first-order vortex induced vibration characteristics of the whole WTGS are studied by using the simulation method of solid fluid combination. Firstly，taking a 2.5 MW and 140 m tower unit as the research object，a tower-blade coupling simulation structure model is established. The resonance frequency and resonance wind speed range of the first-order vortex induced vibration of the whole WTGS are analyzed by modal and CFD simulation，which shows that the wind turbine tower has the risk of first-order vortex induced vibration. Then，a fast simulation method based on solid fluid iteration is proposed to calculate the first-order vortex induced vibration displacement. Considering the coupling effect of the blades on the vortex- induced vibration of the tower，the maximum vibration displacement is obtained. Field tests show that the measured maximum first- order vortex-induced vibration displacement is basically consistent with the simulation results，which verifies the accuracy of the simulation method. © 2024 Science Press.
