Problems solved by technology

This technology has very strict requirements on the friction coefficient of the sliding track. If the friction coefficient of the sliding track is too large, the mass block will not be able to slide.

Embodiment Construction

[0026] The present invention provides a rolling mass tuned damper, and the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 2 , image 3 and Figure 4 As shown, the two gears 3 are respectively fixed on both sides of the large-mass disc 1, and the two arc bearings 2 with racks are fixed and installed side by side on the building structure, leaving a gap in the middle for the passage of the large-mass disc 1 ;The gear 3 meshes with the rack with the rack arc support 2; the large-mass disc 1 is provided with multiple rings of mounting holes along the radius to install the counterweight, and the mass block can be fixed on the disc at different distances from the center of the disc , so that the natural frequency of the system can be adjusted after the installation is completed; a dissipative damping fluid tank is installed under the arc bearing 2 with the rack; when the radius of t...

Abstract

A rolling mass tuning damper belongs to the technical field of energy dissipation and damping of civil engineering structures and is a damping energy consumption device which utilizes the mass tuning damper at the top of a high-rise building to control vibration of the building and reduce structure response under wind load and earthquake load. A gear is fixed with a large-mass round disc, a circular support seat with a rack is fixedly installed on a building structure, the gear is meshed with the rack of the circular support seat with the rack, and a dissipation damping liquid tank or a friction piece is installed on the lower portion of the circular support seat with the rack. When the radius of the large-mass round disc is located at the lowest point of the circular support seat with the rack, the round disc partially stretches into the dissipation damping liquid tank to dissipate energy, or is in friction with the friction piece to dissipate energy. The rolling mass tuning damper is capable of remarkably increasing equivalent mass under the condition that gravity load is not remarkably increased, greatly reduces dynamic response of the structure under horizontal load accordingly, is stable in damping effect, simple in structure, safe, reliable, good in durability, strong in designability and capable of effectively improving comfortableness of the high-rise building.

Description

technical field [0001] The invention belongs to the technical field of energy dissipation and vibration reduction of civil engineering structures, and in particular relates to a rolling mass tuned damper for controlling building vibration and reducing structural response under wind load and earthquake load. Background technique [0002] In recent years, the mass-tuned damper has been widely used as an energy dissipation and vibration reduction device, and its good vibration reduction effect has also been verified by a large number of projects. However, in order to achieve a better shock absorption effect for ordinary mass-tuned dampers, the mass ratio is set to be large, which will significantly increase the structural weight. Normally, it is expected to reach 3%~5% of the original structural mass, and these additional masses will increase significantly. Gravity loads of the structure. [0003] The existing mass-tuned damper systems generally have two types: suspension type...
