摘要：As a flexible structure with the height-to-width ratio being quite large, the wind-power tower structure is easily produce the wind-induced vibration under the action of dynamic wind load. First of all, the probabilistic characteristics of the response of structure and its control system in the frequency domain are analyzed in theory. Secondly, the structural responses of wind load under three conditions, including standard operating condition, cutting condition and limiting condition, are analyzed by the spectral analysis method in practice and the control effect of the damper on the structure is discussed. The results show that the tower structure has different response characteristics under different wind speeds, and the maximum displacement and acceleration of the structure are greatly reduced after the suspension tuned mass damper is set up.
