摘要

the invention relates to a coupling element (32) prepared for attachment between a vibrating body (12) and a tower wall (4) of a tower of a wind power installation (100) in order to influence the relative movement between the vibrating body (12) and the tower wall (4) in order to influence the vibration behavior of the tower, comprising a first fixing section for fixing to the vibrating body (12), and a second fixing section for fixing to the tower wall (4) in order to establish mechanical coupling between the vibrating body (12) and the tower wall (4) through the coupling element (32), the coupling allowing relative movement between the vibrating body (12) and wall tower (4), and the relative movement having a first direction of movement, in which case the first and second securing sections move in one direction towards the other, and a second direction of movement, in which case the first and the second securing sections move one step away from each other, and the coupling element (32) having a spring element for the elastic spring coupling between the first and second securing sections, wherein the spring elastic coupling is described by a spring function, and the spring element being designed in such a way that the spring function is substantially the same for the first and second directions of movement and, in addition or alternatively, the spring element being designed in such a way that movement in the first direction of movement leads to compression of a first spring portion and extension of a second spring portion to the spring element and movement in the second direction of movement leads to extension of the first spring portion and compression of the second spring portion to the spring element in order to equalize the respective spring functions for the first and second directions of movement with the other.
