According to the multistage composite type energy absorption and dissipation damping device, the defect that in the prior art, in complex load action, energy dissipation in multiple directions cannot be conducted is overcome, and multistage and polydirectional damping can be effectively realized. According to the scheme, the device comprises an outer box, a mass block and a liquid container, wherein permanent magnets are arranged on the top and at the bottom of the outer box correspondingly, and magnet poles of the two permanent magnets are opposite; the mass block is arranged inside the outer box, and the side face of the mass block is connected with the inner wall of the outer box through a first elastic damping assembly to realize the energy dissipation and damping effects of the mass block in the horizontal direction; the liquid container is arranged below the mass block, liquid with a set volume is contained in the liquid container, the liquid container is internally provided with a second elastic damping assembly, the bottom end of the second elastic damping assembly is connected with the inner bottom of the liquid container, and the top end of the second elastic damping assembly is fixed to the mass block; and meanwhile in the moving process of the mass block, magnetic induction lines generated by the two permanent magnets are cut to conduct dissipating in the mode that mechanical energy is transformed into electric energy.

Description

technical field [0001] The invention relates to the field of structural engineering vibration control, in particular to a multi-stage composite energy-absorbing energy-absorbing energy-absorbing device, application and method. Background technique [0002] Towering structures such as transmission tower-line systems and communication towers have the characteristics of high structure and strong overall structure flexibility. Once they fail or are damaged, they will cause huge losses to the society. Under the action of earthquake or wind load, the vibration of towering structures is very obvious, collapse and damage occur occasionally, and the vulnerability is high. It is of great significance to reduce the vibration of towering structures such as transmission towers and improve the reliability of towering structures. [0003] The traditional anti-seismic method emphasizes "resistance". It is uneconomical and unreasonable to use the bearing capacity and deformation capacity of...

AI Technical Summary

Problems solved by technology

[0004] However, for high-rise structures such as transmission tower-line systems and communication towers, the direction of the vibration or wind load has strong randomness, and the control of the shock absorption scheme in the prior art is relatively simple, and comprehensive and effective control cannot be achieved. The energy dissipation in one direction is affected, and the dissipation speed is slower. Therefore, further research and analysis of multi-stage composite energy-absorbing energy-absorbing and vibration-absorbing devices suitable for towering structures is required.
