Embodiment Construction

[0086] exist Figure 1 to Figure 9 In , the same reference numerals are used for the same or similar parts or components with the same or similar functions for the sake of simplicity.

[0087] figure 1 View (A) shows a wind energy installation 1000 with a tower 1001 and a pod 1002 mounted on the tower 1001 . The nacelle 1002 carries a rotor 1003 having a plurality, currently three, of rotor blades 1004 . The rotor blades 1004 of the rotor 1003 are connected via a hub 1005 to a shaft (not shown in detail) in the nacelle 1002 . For this purpose, rotor blades 1004 are connected via blade bearings to the hub adapter and coupled to the shaft. In the rotating rotor 103 driven by the wind, a generator arranged in the nacelle 1002 can be driven via a shaft to generate electric current. The electrical energy provided by the generator can be transformed via an electrical converter, transformer or similar other suitable electrical device for feeding into a grid not shown in detail; s...

Abstract

The invention relates to a vibration-reducing module, comprising a bearing structure (150), a pendulum system (101) having a pendulum mass (110) and having a suspension system (120) for suspending the pendulum mass on the bearing structure, wherein the suspension system has a number of pendulum spring elements (140) and a pendulum mass suspension extending between the pendulum mass and the bearing structure in the direction of a suspension axis, and wherein the pendulum mass suspension is fastened via the suspension head (170) thereof to the bearing structure. According to the invention, it is provided that the pendulum mass suspension is fastened via a joint head to the bearing structure, which has a pendulum bearing designed as a sliding bearing, and at least one pendulum spring element of the number of pendulum spring elements extends in the direction of the suspension axis between the pendulum mass and the bearing structure.

Description

technical field [0001] The invention relates to a vibration limiting module according to the preamble of claim 1 . Furthermore, the invention relates to a plant with such a vibration limiting module as well as to a construction segment for a construction installation with such a vibration limiting module and to a wind power plant with a tower and a tower section with such a vibration limiting module facility. Background technique [0002] Wind energy installations (WEA) are particularly susceptible to vibrations due to their high and here elongated construction; this applies in particular to steel tube towers and prestressed concrete towers of wind energy installations, which are increasingly Designed for higher hub heights which increases susceptibility to disturbing vibrations. In particular, resonance phenomena of a rotating rotor with likewise vibrating rotor blades can cause complex vibration patterns of the wind energy installation, especially also at its tower. At ...
