TMD vibration damper for ultrahigh wind turbine generator stand column
The invention discloses a TMD vibration damper for an ultrahigh wind turbine generator stand column. The TMD vibration damper comprises four sets of top supports, a mass ring, wire rope vibration isolators, dampers, a tool support and the like. Each set of top supports includes the two top supports. The top supports are uniformly distributed on the periphery of the outer portion of a stand columnand used for fixing and suspending mass blocks. Lifting lugs are welded to the upper portion of the mass ring so that the mass blocks can be suspended more conveniently and safely through wire ropes.The TMD vibration damper is provided with the four viscose dampers which are uniformly distributed above the corresponding wire rope vibration isolators. Each viscose damper and a corresponding springsupport share a base plate and can achieve the effect of dissipating energy. When the tower type stand column sways due to external excitation, the mass ring can do motion opposite to the structure all the time and generate counter-acting force to be acted on the main structure through the design of annular machines ring TMDs so as to control vibration of the structure no matter how to sway in any direction. The TMD vibration damper achieves the purposes of energy dissipation and vibration reduction through the viscose dampers.
本发明公开了一种用于超高型风电机立柱的TMD减振装置，包括顶部支架，质量环，钢丝绳减振器以及阻尼器以及工装支架等。所述的顶部支架共四组，每组两个，均匀的分布在立柱外部周围，是为了来固定悬挂质量块；所述质量环在上方焊接吊耳，以便钢丝绳能更加方便，安全的悬吊住质量块；所述的粘滞性阻尼器共四个，均匀的分布在每个钢丝绳减振器的上方，与弹簧支座共用一个垫板，可以起到耗散能量的作用。当塔状立柱因为外部激励而产生晃动时，依靠环形质量环TMD的设计，无论从哪个方向产生的晃动，质量环都能产生始终与结构相反的运动，产生反作用力于主结构上，从而控制结构的振动，并通过粘滞性阻尼器达到耗能减振的目的。
