Description
Technical field
This utility model relates to a kind of multiple tuned mass dampers damping control device, shakes for wind or earthquake response
Vibration control, belong to structural vibration control technical field.
Background technology
Tuning quality vibration damping controls technology and belongs to Structure uniformity.Conventional tune mass damper (tuned mass
Damper, is called for short TMD) it is made up of mass, spring, damping unit.When there is external excitation, TMD system
The inertia force that relative motion produces reacts in structure, produces structural vibration and controls.Damping in TMD system
Device is also by performance power consumption effect, thus reaches to reduce the purpose of structural vibration reaction.TMD successful Application at present
Shake and earthquake response in control structure wind.Passive tuned mass damper, TMD (PTMD) be a kind of receive much concern build

GB5011-2010) still fail to be correlated with PTMD regulation provision, reflects, existing achievement in research also cannot be to PTMD
Aseismatic Design provides enough theory support.The internationally famous structure control experts such as Sheldon Cherry, T.T.Song
Expressing similar views the most respectively on different workshops and resolve damping frequency bandwidth problem, PTMD exists
By great development prospect in Application in Building.When PTMD frequency is close to environmental excitation (such as earthquake, wind load etc.) frequency
Time just play press down use of bestirring oneself.Owing to existing PTMD is the design of simple substance point, its natural frequency of vibration is single, can only be at knot
Play a role near certain single order frequency of vibration of structure.And for seismic frequency relatively wind load frequency, its frequency that shakes is wider and high
Frequently composition highlights, and building structure can be excited to produce multiple mode of oscillation, cause PTMD damping frequency and building vibration
Frequency is difficult to complete match.This is also the main cause that current PTMD shockproof control is not as effective as that wind dynamic control.
To this, there is the method that scholar proposes MTMD, it may be assumed that PTMD (each PTMD of multiple single-degree-of-freedom is installed under construction
The natural frequency of vibration is the most identical), thus form the PTMD group with certain frequency bandwidth.But also have research to think:
When using MTMD in earthquake, other vibration shapes outside controlling may be played amplification by a certain PTMD, i.e. lead
Cause " vibration shape pollution ".At present, the problem of PTMD damping frequency bandwidth how is effectively improved also the most fundamentally
Solve.
