Background
With the continuous progress of wind power technology, the wind turbine generator set presents a large development trend. In order to obtain better quality wind energy resources and meet the installation requirement of the large-diameter wind wheel, the tower barrel of the wind turbine generator is continuously lifted, and therefore the flexibility of the tower barrel is increased. Under the action of the ambient wind speed, periodical shedding vortex is easy to form at two sides of the tower barrel, and periodical lifting load is generated, so that vortex-induced vibration of the tower barrel is caused, and particularly for an elastomer of the high-flexibility tower barrel, when the vortex-shedding frequency is close to or equal to the natural frequency of the tower barrel, vortex-induced resonance is caused, so that the tower barrel is greatly vibrated, and fatigue damage is caused. The vortex-induced vibration is that when wind is at the side of a cabin in the shutdown process of the wind turbine, wind is used as fluid to flow through the tower and the outside of the blades to form a double-column flow-around phenomenon, and the acting force generated by the phenomenon is far greater than the force generated by vortex shedding of a single tower; wake flow falling vortex flowing through the tower barrel can generate acting force on the unit, the falling frequency of the acting force is consistent with the first-order frequency of the unit of the tower barrel with the height of 90m, resonance is formed, and the resonance problem is that the value is amplified due to double-column flow around superposition generated by the long blades and the tower barrel, and the unit vibration is continuously amplified due to the frequency locking phenomenon of the falling vortex.
