Abstract

The invention provides a space multi-link anti-sway device, and belongs to the technical field of three-dimensional shock insulation and shock resistance. According to the technical scheme, the devicecomprises a base, and an upper structure opposite to the base; two multi-link anti-sway assemblies and a bearing structure are respectively arranged between the base and the upper structure; the bearing structure is positioned between the two multi-link anti-sway assemblies; and the top of the bearing structure is connected to the upper structure and the lower portion of the bearing structure isarranged on the base. The space multi-link anti-sway device has the beneficial effects that the sway deformation of the upper structure is converted into the tension and compression deformation of a stress rod part by means of the transmission of stress deformation of the space multi-link anti-sway parts, so that the anti-sway effect can be achieved through the tension and compression rigidity ofthe stress rod part.

Description

technical field [0001] The invention relates to the technical field of three-dimensional shock isolation and shock resistance, in particular to a space multi-link anti-sway device. Background technique [0002] The traditional seismic isolation technology cannot reduce the vertical response of the structure, and the structural damage caused by the vertical earthquake cannot be ignored. The three-dimensional seismic isolation technology has become an urgent problem to be solved. [0003] At present, in order to achieve the three-dimensional seismic isolation effect, the vertical dynamic stiffness of the three-dimensional seismic isolation structure is usually low, the anti-sway and overturning ability of the isolation layer is weak, and the structure is in danger of swaying and overturning. How to solve the problem of swaying and overturning the upper structure is a One of the difficulties in conducting 3D seismic isolation research. Many three-dimensional seismic isolation ...
