Self-adaptive adjusting tuned mass damper and using method thereof

Abstract

The invention relates to the field of building anti-vibration equipment, in particular to a self-adaptive adjusting tuned mass damper and a using method thereof. The self-adaptive adjusting tuned massdamper comprises a first rack fixed to a building body, the first rack is horizontally arranged, a mass body is connected to the first rack in a sliding mode, the self-adaptive adjusting tuned mass damper further comprises an energy consumption mechanism fixed to the building body, an energy conversion mechanism is arranged on the mass body, the mass block is in transmission connection with the energy consumption mechanism, a flow adjusting mechanism is arranged on the energy consumption mechanism, and the energy conversion mechanism is electrically connected with the flow adjusting mechanismthrough a wire. According to the self-adaptive adjusting tuned mass damper and the use method thereof, the mass body drives the energy conversion mechanism to convert impact energy into electric energy, so that the energy consumption mechanism is adaptively adjusted, corresponding adjustment is made according to the size change of external excitation, the anti-vibration range is expanded, and better damping and protection effects on the building body are achieved. Moreover, the mass of the whole device does not need to be changed, and the self-adaptive adjusting tuned mass damper is simple instructure and easy to implement.

Description

technical field [0001] The invention relates to the field of building anti-vibration equipment, in particular to an adaptively adjusted tuned mass damper and a use method thereof. Background technique [0002] In order to improve the anti-vibration and wind resistance of high-rise buildings, tuned mass dampers are usually installed inside high-rise buildings in order to reduce the structural vibration of high-rise buildings and protect high-rise buildings. [0003] The existing tuned mass damper achieves the purpose of protection and anti-vibration by adjusting the frequency to be close to the main structure and changing the resonance characteristics of the structure. However, since the adjustment of the frequency is related to the mass of the main body of the building, if the mass of the main body of the building is huge, the tuning mass will be caused. The structure of the damper is heavy and not easy to implement, and the existing tuned mass damper cannot adjust the dampi...

[0003] The existing tuned mass damper achieves the purpose of protection and anti-vibration by adjusting the frequency to be close to the main structure and changing the resonance characteristics of the structure. However, since the adjustment of the frequency is related to the mass of the main body of the building, if the mass of the main body of the building is huge, the tuning mass will be caused. The structure of the damper is heavy and not easy to implement, and the existing tuned mass damper cannot adjust the damping size according to the change of the external excitation, so the vibration resistance range of the existing tuned mass damper is limited , when the main body of the building is subjected to a large external excitation, its anti-vibration effect is poor, which is not conducive to the protection of the main body of the building. In view of this, we propose an adaptively adjusted tuned mass damper and its use method
