Description
Technical field
The invention belongs to the horizontal vibration control device technical fields of civil engineering structure, and in particular to a kind of roller ten thousand
To type horizontal tuned mass damper.
Background technology
Structural vibration tuning quality damps (TMD) control device as a kind of dynamic vibration absorber, in high-rise and tall and slender structure,
Before large span has a wide range of applications with dynamic response control aspect of the soft structure under wind, earthquake and Pedestrian Load equal excitation
Scape.This device has apparent control effect to the vibration of structure, and the influence to building function is smaller, only takes up few build
Area is built, is easily installed, repairs and replaces.
TMD is made of mass block, elastic element, three big component of damping element, and maximum component is inertia mass.Inertia matter
The key technology that the supporting way in main structure is TMD devices is measured, it need to ensure that inertia mass and the main structure vibration shape are humorous
Center of percussion has determining natural vibration period and damping.The inertia mass of TMD systems may be used multistage pendulum, inverted pendulum, hydraulic support system,
Laminated rubber bearing etc. is hung or support：
More vertical sky need to be occupied using the single-stage rocking suspension and multistage rocking suspension, suspension arrangement of suspension system
Between；
Using laminated rubber bearing support system, when dynamic excitation is smaller, TMD can not vibrate, and can not play a role；
The common system supported using track, then require track to have enough rigidity, cannot when supporting inertia mass
There is larger deformation, not resistance excessive caused by inertia mass is slided.In addition, track support TMD generally exist can not
The friction avoided, to TMD, there is adverse effects for friction：1, when dynamic excitation is smaller, i.e., structure is in microvibration, TMD
The inertia force of exercise quality block is possible to that its stiction can be less than, to make TMD be in the lock state, TMD also just temporarily funerals
The function of energy-obsorbing and damping is lost；2, when controlled structures are carried the load action of shock feature by earthquake etc., excessive friction
The startup time that TMD can significantly be delayed, so as to cause the decline of control effect.
TMD control strategies are to achieve the purpose that dynamic absorber using the resonance of the controlled damping type of minor structure and main structure, are controlled
The optimal vibration frequency of device processed should be tuned as the natural frequency of vibration that main structure is controlled damping type.Overwhelming majority building in Practical Project
Object is not that quality, rigidity are full symmetric, that is, the vibration frequency in each direction is different.Unfavorable work is generated to structure
External drive direction is nor determine unique.Therefore, it is necessary to structure different directions using different vibration frequencies
TMD, to reach the optimum efficiency of tuning vibration damping.
