Embodiment Construction

[0035] Embodiments of the present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. In order to clearly show the internal structure and connection relationship of each component, some components in the drawings (for example, the Figure 1 to Figure 6 The housing of the damper in ) is shown as a transparent structure.

[0036] The following will refer to Figure 1 to Figure 6 The specific structure of the damper 100 for the tower of the wind power generating set according to the embodiment of the present invention will be described in detail.

[0037] The damper 100 according to the embodiment of the present invention includes a housing 110 . The casing 110 contains liquid L to suppress the second-order vibration of the tower of the wind power generating set through the inertial force or sloshing of the liquid L. Specifically, the vibration damping effect can be provided by the i...

Abstract

The invention provides a tower of a wind power generator set and a damper for the tower of the wind power generator set. The damper comprises a shell which contains liquid, and second-order vibrationof the tower of the wind power generator set is suppressed by inertia force or shaking of the liquid. By the tower of the wind power generator set and the damper for the tower of the wind power generator set, negative effects caused by second-order vibration on the tower in a gale environment can be reduced, and accordingly safety of the tower is improved.

Description

technical field [0001] The invention relates to a damper for a tower of a wind power generating set and the tower of the wind generating set. Background technique [0002] For the tower of the wind turbine, according to the principle of vortex-induced vibration, when the wind blows through the tower, an anti-symmetrical vortex street is generated at the rear end of the tower. When the vortex falls off the surface of the tower, it will affect the tower. The change of the pressure on the surface of the cylinder, the change of the pressure produces an excitation to the tower, the dimensionless number Strouhal number St (Strouhal number) is the similarity criterion introduced in the discussion of physical similarity and modeling in fluid mechanics, for such as the tower Flow around the cylinder of the cylinder, St=fD / V, where f is the vortex separation frequency, D is the characteristic length (ie, the outer diameter of the tower), and V is the fluid velocity (ie, the wind speed...
