Description
Technical Field
The invention relates to the technical field of vibration control, relates to the field of dampers, in particular to a multi-dimensional high-performance damper which can be applied to multi-dimensional vibration reduction control of a large-span space structure.
Background
With the daily and monthly variation of world science and technology and the daily improvement of people's cultural level, people put higher demands on building spans, and large-span space structures are generated as hot spots in the field of structural engineering, and are rapidly developed on the basis. The structural dynamic response of the large-span space structure under the actions of earthquake, wind vibration and the like is strong. How to reduce the dynamic response of the structure and improve the earthquake resistance and wind resistance of the structure becomes the problem to be solved urgently at present. The traditional anti-seismic method is to improve the structural rigidity, and absorb energy generated by wind vibration, rain vibration, environmental vibration, earthquake action and the like by means of the energy consumption capability of the structure, so that the effect of reducing dynamic response to a certain extent can be achieved under the effects of small and medium earthquakes and non-strong wind; however, the structural part is inevitably damaged or destroyed under the action of strong shock or strong wind, which is unsafe and unreasonable to some extent. Therefore, in order to overcome the defects of the traditional anti-seismic method, the structure vibration control technology is gradually raised, and the damper is widely applied to anti-seismic vibration reduction of modern civil engineering buildings. The damper vibration damper device on the market at present can only resist the pulling and pressing action in the axial force direction, can only be used for vibration resistance and vibration reduction of the supporting member in the structure, and is mainly applied to high-rise and super high-rise buildings; unlike support members in high-rise and super-high-rise building structures, the multi-dimensionality of the loading direction of the large-span space structure and the multi-dimensionality of the internal forces of the structure result in that the structural members are usually under the combined action of bending moment and axial force and the multi-dimensional internal forces, and the damper with the capacity of resisting the axial force only cannot realize the vibration reduction and energy consumption of the members in complex stress states and is not suitable for the large-span space structure. The existing damper vibration reduction device is difficult to meet the vibration control requirement of a large-span space structure.
