Abstract

The invention discloses a tuned mass damper for a tower. The tuned mass damper comprises a mass ball suspended in a tuned mass damper body, a hemispherical plate arranged in the tuned mass damper body and positioned below the mass ball, and a plurality of elastic mechanisms used for connecting the mass ball with the side wall of the tuned mass damper body and uniformly distributed in the circumferential direction; each elastic mechanism is composed of a damper and a spring arranged outside the damper in a sleeving mode, and universal joints are arranged at the two ends of each elastic mechanism; and the tuned mass damper body is composed of a top cover plate, a bottom fixing ring and a plurality of vertical supporting rods which are used for connecting the top cover plate and the bottom fixing ring and are evenly distributed in the circumferential direction. According to the tuned mass damper, omnidirectional tuning can be realized, the structure is simple, the construction is convenient, dynamic response control can be effectively carried out on the wind load vortex-induced vibration of a flexible tall tower, and the safety and reliability of the flexible tall tower are ensured.

Description

technical field [0001] The invention relates to the technical field of vibration reduction in construction engineering, in particular to a tuned mass damper for towers. Background technique [0002] With the development of chemical tower equipment in the direction of large-scale, the tower tube is the main load-bearing component of the tower, and the height of the tower tube is getting higher and higher, and the risk of vortex-induced vibration is also increasing. The tall tower is a structure with high height and soft lateral stiffness, so it will cause a large structural response under the action of horizontal wind load, and it is easier to generate wind load resonance under the action of Karman vortex street, and it is similar to a chemical tower Such towering buildings are getting taller and taller, and the materials used tend to be light and high-strength, which increases the flexibility of the structure, reduces the damping, and is more sensitive to the action of wind....
