Omni-directional tuned mass damper for flexible tower drum of wind turbine generator system
The invention discloses a tuned mass damper, and provides an omni-directional tuned mass damper for a flexible tower drum of a wind turbine generator system. The omni-directional tuned mass damper forthe flexible tower drum of the wind turbine generator system guarantees the safe reliability of the flexible tower drum. The technical problems that in the prior art, the vortex-induced vibration control cost is high, and the construction is difficult along with the increase of the height of the tower drum are solved. The omni-directional tuned mass damper for the flexible tower drum of the windturbine generator system comprises counterweight mass blocks. The counterweight mass blocks are supported on the bottom surfaces of the interiors of supporting frames in a sliding mode, one end of each upper supporting spring and one end of each lower supporting spring are hooked at the upper end of the corresponding counterweight mass block and the lower end of the corresponding counterweight mass block respectively, the other end of each upper supporting spring and the other end of each lower supporting spring are horizontally hooked on the corresponding supporting frames, and therefore thecounterweight mass blocks can be kept in a stable supporting state.
本发明公开了一种调谐质量阻尼器，提供了一种保证柔性塔筒安全可靠性的风力发电机组柔性用的全向调谐质量阻尼器，解决了现有技术中存在的塔筒随着高度的增加，涡激振动控制成本高，施工困难等的技术问题，它包括配重质量块，所述配重质量块滑动支撑在支撑框架内的底面上，且配重质量块的上、下两端分别钩挂着若干个上支撑弹簧和下支撑弹簧的一端，上支撑弹簧和下支撑弹簧的另一端分别水平钩挂在对应的支撑框架上，使配重质量块保持平稳支撑状态。
