, large span light-duty in structure, Super High, form complexity feature.This class formation is also easy to produce larger change under dynamic load function
Shape and vibration.Vibration, which occurs, for structure can not only make top personnel generate discomfort, excessive deformation and vibration knot easy to increase
The internal stress of structure reduces structure durability, and What is more will lead to structure destruction, threat to life property safety.
How vibration damping is carried out to civil engineering structure, new challenge is proposed to numerous researchers.Traditional structure vibration
Control technology is contacted using reinforcement structure, increases component section, to improve the rigidity of structure, reduces structural amplitude, control structure vibration
It is dynamic.But this will increase the quality of structure, increase the consumption of material, and can greatly increase difficulty of construction.Therefore, structure is carried out
Vibration control becomes hot topic in recent years.
Whether need extra power according to control measure, structural vibration control be generally divided into active control, semi- active control,
Passive control and mixing control.Wherein, damper is the core component of control device, and the selection of damper directly affects control energy
The quality of power.Active control device reduces the dynamic respons of structure using additional energy input, although its control effect is good, adapts to
Property it is strong, but technology is complicated, involve great expense, maintenance requirement is high, and engineer application has larger difficulty.Passive control does not need external energy
Input, main rigidity, the size of damping and quality and its distribution in structural system for changing structure by design, Huo Zhegai
Become the transmission path of external load, to achieve the purpose that control engineering structure response, technology is easy, cheap, practical application energy
Power is strong, and also has preferable effectiveness in vibration suppression.
The damping mechanism of TMD (Tuned Mass Damper) is: adding a small quality power in principal oscillation system and disappears
Vibrating system.When meeting Damper System response lag when the condition of principal oscillation system response pi/2, the elastic force of Damper System at this time
Viscosity resistance is equivalent to main vibrating system, inhibits the displacement of main vibrating system, so that the vibration of main vibrating system is reduced to the maximum extent,
Achieve the effect that vibration damping.Eddy-current damping is a kind of physical phenomenon based on electromagnetic induction principle.When non-magnetic conductor is in magnetic
In when cutting magnetic induction line movement, consecutive variations will occur for the magnetic flux across conductor.According to Faraday's electromagnetic induction law,
Corresponding induced electromotive force can be generated in conductor, to form the similar electric current being vortexed, i.e. current vortex.According to Lenz's law, electricity
Vortex can generate a new magnetic field opposite with magnetic field simultaneously, form the damping force for hindering the two relative motion.So
The result of circulation eventually leads to vibrational energy and is consumed by the resistance fuel factor of conductor, and here it is eddy-current dampings.At this
During one, the kinetic energy of conductor plate and magnetic field relative motion is first changed into electric energy, then thermal energy consumption is converted into conductor plate, in
It is to play the role of passive energy dissipation.Eddy current damper has durability good, easy for installation by the way of contactless energy consumption
The advantages that, it is used widely.
How eddy-current damping is increased as research hotspot in recent years, and increasing through conductor magnetic flux change rate is to increase
The key for adding damper to consume energy mainly passes through three kinds of effective ways, i.e. increasing magnetic field, increase conductor thickness and increase conductor
The speed of cutting magnetic induction line.Permanent magnet magnetic field intensity is bigger, not only claims to magnet material, but also will increase declining for magnetic field
The rate of deceleration, design and construction difficulty can be increased, moreover, both methods is equal to the quality outside device plus by increasing copper plate thickness
It will increase dramatically cost.The present invention increases the speed of conductor cutting magnetic induction line using mechanical leverage system, effectively improves energy consumption effect
Fruit.
