Abstract

The invention discloses a combined basin-shaped hybrid tuning damper for a wind power generation tower. The combined basin-shaped hybrid tuning damper is characterized in that damping units forming the damper comprise a flat cylinder body and a mass block, wherein the flat cylinder body is provided with cylinder walls and a bottom plate, the top faces of the cylinder walls are connected with upper flanges, the bottom faces of the cylinder walls are connected with lower flanges, and damping liquid is contained in the flat cylinder body; the flat cylinder body is horizontally fixed to the top face of an engineering structure by means of the lower flanges; a universal wheel is arranged at the bottom of the mass block which is placed on the bottom plate of the cylinder body, and the mass block can move in any direction on the bottom plate through the universal wheel; springs are distributed uniformly on the periphery of the mass block, the mass block is connected with the springs in a radiation shape, and the other end of each spring is connected to the corresponding cylinder wall of the cylinder body, and the number of the springs is not less than three.

Description

technical field [0001] The invention belongs to the technical field of structural engineering vibration control, and in particular relates to a combined basin-type hybrid tuning damper of a wind power tower. Background technique [0002] With the development of the global economy, the consumption of natural resources continues to increase, and the large-scale exploitation and use of non-renewable energy such as coal, oil, and natural gas not only puts a huge pressure on the continuous supply of energy, but also brings about the greenhouse effect, acid rain, smog, etc. Environmental issues. Wind power generation has the advantages of clean and pollution-free, large single-unit capacity, and good economic benefits. In recent years, the wind power industry has developed rapidly around the world, and the single-unit capacity of wind turbines has become larger and larger. During normal operation, due to the periodic rotation of the impeller, it is subjected to cyclically changin...
