Abstract

The invention discloses a movable small ball type suspension collision damper, and particularly relates to the field of civil structure vibration control. The movable small ball type suspension collision damper comprises a hollow supporting frame; a universal hinge is arranged on the supporting frame; a suspension rod is arranged at the bottom of the universal hinge; a hollow mass block is arranged at the free end of the suspension rod; a metal ball is arranged in the mass block in a rolling mode; viscoelastic materials are arranged on the inner surface of the supporting frame and the inner surface and the outer surface of the mass block; and the supporting frame is further located on a motion trail of the mass block. According to the technical scheme, the problem that structural vibration of a building is prone to being caused under the action of wind loads or earthquakes is solved, and the wind resistance and vibration reduction performance of the building can be improved.

Description

technical field [0001] The invention relates to the field of vibration control of civil structures, in particular to a movable ball type suspension collision damper. Background technique [0002] With the development of society, more and more high-rise buildings rise from the ground, more and more bridge structures are used to cross mountains, rivers, lakes and seas, and with the advancement of science and technology, their engineering structures become more and more diverse. Materials have also become lightweight and strong. But no matter what kind of structure, under the action of strong wind load and earthquake load, it will produce different degrees of vibration, which may lead to collapse in severe cases, which makes it difficult for the structure to meet the requirements of comfort and safety. How to improve the anti-vibration and wind resistance of buildings, and reduce the damage caused by wind load or earthquake to buildings has become an urgent problem to be solve...
