A rolling ball multi-directional damping control device

Abstract

The invention discloses a roll ball type multidirectional damping control device comprising a semi-closed cylindrical structure, a hollow metal mass ball, an inwards concave type hook face bearing table, springs and anti-collision rubber. The semi-closed cylindrical structure and the inwards concave type hook face bearing table are connected, and the inwards concave type hook face bearing table is internally provided with the hollow metal mass ball. The springs are arranged on the connection positions of the semi-closed cylindrical structure and the inwards concave type hook face bearing table. The hollow metal mass ball rolls in the inwards concave type hook face bearing table in any direction, and when a structural object is under horizontal motivation, large damping force is generated. Liquid is injected into the hollow metal mass ball, and the liquid in the hollow metal mass ball and the hollow metal mass ball form a tuned liquid damper so as to supply damping force to a structure. The purpose of horizontal-direction multi-stage vibration control is achieved; and meanwhile, when the structural object is under vertical motivation, through vertical movement of the inwards concave type hook face bearing table, by means of the method that the hollow metal mass ball impacts the top rubber to consume energy, vertical vibration of the structure is controlled.

Description

technical field [0001] The invention relates to the field of building structures, and is a ball-type multi-directional damping control device, which is mainly used in the damping control of some important long-span, towering and other related engineering structures. Background technique [0002] As my country's construction industry enters a stage of rapid development, the height and complexity of buildings are also constantly increasing, and with the advancement of various technologies, the application of some lightweight and high-strength materials is becoming more and more extensive, making the structural Stiffness and damping ratios become smaller. The structure will produce significant dynamic response under the action of earthquake and wind load, which will seriously threaten the safety of the building and reduce the comfort of the building. Moreover, in recent years, due to the frequent occurrence of earthquakes and wind and rain disasters, a large number of building ...

Problems solved by technology

[0008] At present, many important structures in actual engineering will consider the application of vibration damping devices. Most of the traditional vibration damping control devices can only control vibration in one direction or in a few specific directions. Considering the complexity of structural vibration, Such a vibration damping control device cannot well meet the requirements of vibration control
