AI Technical Summary

Technical Problem

Traditional tuned liquid column dampers are difficult to effectively control the vibration response of wind turbine support structures in multiple directions, especially under multi-directional and uncertain environmental excitations such as wind, waves, and earthquakes, where the vibration reduction effect is limited.

Method used

A multi-column annular tuned liquid column damper is designed, which adopts a vertical tube column and annular flow channel structure. The vertical tube columns are distributed in annular array inside the tower, and the annular flow channel is formed by bending pipes and T-shaped tees to optimize the liquid flow path and enhance the energy dissipation effect. The symmetry of the vertical tube columns covers multiple horizontal directions.

Benefits of technology

It significantly improves the vibration reduction efficiency of wind power support structures in multiple directions by 5% to 10%, reduces material usage and space occupation, simplifies installation and maintenance processes, and improves production efficiency and vibration reduction effect.
