Problems solved by technology

However, the existing jacket-type tuned damper has two obvious defects: (1) the inherent damping is small, and the energy dissipation capacity and vibration control ability are weak; (2) the welded joints in the jacket-type support are extremely Easy to fatigue, unable to meet the fatigue resistance performance of offshore wind turbines under dynamic response

Abstract

The invention relates to a tuned damper of a controllable jacket type marine wind-driven generator. The tuned damper comprises an external damping cavity unit (1) which is arranged on the ground in asliding manner and an internal damping internal damping unit (5) which is arranged on the external damping cavity unit (1) in a sliding manner, wherein the outer wall of the external damping cavity unit (1) is connected with the wind-driven generator through energy consumption springs (4); a cavity (10) which is sunken downwards is formed in the middle part of the external damping cavity unit (1);the internal damping cavity unit (5) is arranged on a bottom plate of the cavity (10) in a sliding manner; the side wall of the internal damping cavity unit (5) is connected with the inner wall of the cavity (10) through the energy consumption springs (4); the inner part of the external damping cavity unit (1) and the inner part of the internal damping cavity unit (5) are sealed; and liquid (2) is loaded in the external damping cavity unit (1) and the internal damping cavity unit (5), and air is left. Compared with the prior art, the tuned damper disclosed by the invention has various energyconsumption mechanisms under the effect of wind or / and earthquake, and the energy consumption capacity is high.

Description

technical field [0001] The invention relates to the technical field of vibration control of civil structures, in particular to an adjustable jacket-type tuning damper for offshore wind power generators. Background technique [0002] As a renewable energy source, wind energy has attracted much attention over the past few decades. Although the corresponding installations have an extremely long historical background, modern wind turbines only took shape in the early 20th century, such as Denmark, Germany, the United States, India and Italy (Vestergard, Brandstrup, & Goddard, 2004). In the past time, offshore turbines have received more and more attention because of their stability and high efficiency. At the same time, new problems in the impact of sea waves and special structures have also attracted extensive attention in the engineering community. [0003] Generally speaking, the supporting structures of offshore wind turbines mainly consist of monopile, tension leg platform...
