According to the application, the constraint damping structure 200 is arranged on the outer peripheral side of the wall of the tower drum 110, so that the difficulty in arranging the constraint damping structure 200 on the wind power tower 100 can be greatly reduced, and the use space inside the tower drum 110 is not influenced. Meanwhile, the application utilizes the characteristics of viscoelasticity of the damping layer 210 and the characteristics of rigidity of the cylinder wall of the tower cylinder 110 and the constraint layer 220, when the tower cylinder 110 vibrates in a bending mode, the damping layer 210 connected with the tower wall can deform along with the tower cylinder 110, and the constraint layer 220 arranged outside the damping layer 210 can generate constraint action on the deformation of the damping layer 210, so that shear strain energy consumption is generated between the cylinder wall and the constraint layer 220 due to the deformation difference of the cylinder wall and the constraint layer, thereby improving the damping performance of the tower cylinder 110, reducing the local strain of the tower cylinder 110, providing a certain degree of vibration reduction effect for the wind power tower 100 under complex power response, and reducing the risk of fatigue failure of the wind power tower 100.

Further, the size of the constraint damping structure 200 is limited, so that the installation difficulty of the constraint damping structure is reduced, the optimal damping effect is provided for the wind power tower 100, and the utilization efficiency of the materials of the constraint layer 220 and the damping layer 210 can be improved.
Preferably, the height between the bottom and the top of the tower 110 ranges from 80m to 150m, the constraint damping structure 200 is disposed at a position of the tower 110 at a height H from the bottom thereof, the height H is a distance between the bottom end of the constraint damping structure 200 and the bottom of the tower 110, and ranges from 0m to 20m, the length of the constraint damping structure 200 in the vertical direction is set to L, and the length L is a distance between the bottom end and the top end of the constraint damping structure 200, and ranges from 5m to 20 m.
In one embodiment, the constraining layer 220 is disposed on the surface of the damping layer 210 away from the tower 110, and surrounds the damping layer 210, so that when the damping layer 210 deforms along with the tower 110, the constraining layer 220 can fully constrain the deformation of the damping layer 210, so as to improve the damping performance of the constraining damping structure 200, and further enhance the vibration reduction effect on the wind power tower 100.
Preferably, the damping layer 210 is made of a polymer viscoelastic damping material, such as a resin material or a rubber material, and the constraint layer 220 is made of a rigid material with a high elastic modulus, such as a steel material or reinforced concrete.
In one embodiment, the circumferential side of the constraint damping structure 200 is further provided with an annular fastening component, so that the tower 110, the damping layer 210 and the wall of the tower are tightly connected, and interlayer sliding of the preset damping structure is avoided, and damping performance is prevented from being affected.
Preferably, the fastening assembly includes two groups respectively disposed at the upper and lower ends of the constraint damping structure 200 to fix the upper and lower ends of the constraint damping structure 200. In one embodiment, the fastening assembly includes two semicircular ferrules and fastening bolts, the two semicircular ferrules being fitted around the circumference of the constraint layer 220 and being coupled and fastened to each other by the fastening bolts, to fix the constraint damping assembly at a predetermined position of the tower 110 and to maintain tight coupling.

Wherein, the constraint damping structure 200 includes a damping layer 210 and a constraint layer 220, and the damping layer 210 is disposed between the constraint layer 220 and the wall of the tower 110. By arranging the constraint damping structure 200 at a preset height of the tower 110, the viscoelastic property of the damping layer 210 and the rigidity characteristics of the wall of the tower 110 and the constraint layer 220 are utilized, so that the damping layer 210 can be bent and deformed along with the tower 110 when the tower 110 vibrates in a bending mode, the constraint layer 220 further limits the bending and deformation of the damping layer 210 along with the tower 110, and further the damping layer 210 generates shear strain energy consumption between the wall of the tower 110 and the constraint layer 220, so that the damping performance of the tower 110 is improved, the local strain of the tower 110 is reduced, a certain vibration reduction effect is provided for the wind power tower 100 under a complex dynamic response, and the risk of fatigue failure of the wind power tower 100 is reduced.
