Abstract

The invention discloses a vibration absorber for a cycloid type wind driven generator tower. The vibration absorber comprises a mass block and a steel wire rope, wherein a rubber rod is connected on the mass block; a connector is sleeved on the steel wire rope; one end of the steel wire rope is connected with a steel wire rope expansion head, and the other end of the steel wire rope is provided with a connecting installation hole; and the connector and the mass block are in a threaded connection. The damper absorbs the structure vibration energy by the swinging of the mass block, and simultaneously dissipates the energy through the axial deformation of a connected rubber spring. The movement direction of a mass cycloid is reverse to that of the structure for the action of dynamically damping; one end of the rubber spring is fixed on the mass block, and the deformation is controlled by the mass block to provide a force which is always reverse to the movement direction of the mass block, and the axial deformation of the rubber spring will have the function of consuming energy. The vibration absorber is simple to design and manufacture, convenient to install and change, has stable hysteretic characteristic, relatively low manufacture cost, and is applied to the structure for remarkably absorbing vibration.

Description

technical field [0001] The invention relates to a vibration reduction and energy consumption device for a tower structure of a wind power generator, which is mainly used in the field of engineering vibration reduction of a wind power generator tower, and can effectively suppress the vibration response of the structure under the action of a fluctuating wind load, and particularly relates to a wire Vibration damping device for pendulum wind turbine tower. Background technique [0002] Frequency-tuned mass damper (TMD) is one of the devices for passive tuning and damping control of structures. TMD consists of mass, spring and damping system. Generally, its vibration frequency is adjusted to be close to the frequency of the main structure, and the resonance characteristics of the structure are changed to achieve the effect of vibration reduction. So far, a variety of TMD dampers have come out, but they are mainly used in the construction field, and there are few TMD dampers fo...
