Abstract:The increases of height and blade size of the wind turbine structure and the high-rise tower structures may generate obvious dynamic responses and large amplitude displacements, even happen with fatigue, buckling, sloping or overturning accidents under wind load. In this paper, taking a wind turbine structure of 1.5 MW as an example, the finite element model under wind load was established with ABAQUS software to analyze the vibration responses under the non-controlled status compared with other schemes of installing single tuned mass damper( STMD ) , bi-tuned mass dampers ( BTMDs) and quad-tuned mass dampers ( QTMDs ) , so as to put forward feasible suggestions for vibration control methods and effectively reduce the probability of accidents. The numerical results showed that when STMD was installed, the peak acceleration on the top of the wind turbine tower decreased by 37. 89% . Compared with non-controlled status, STMD had a good effect on the vibration control of the wind turbine, and the damping effect of installing STMD was better than BTMDs and QTMDs under the action of only low-order vibration mode.
