Adjustment structure vibration, belongs to civil structure (including skyscraper, tall and slender structure and bridge structure etc.) shake control field.
Background technique
With the rapid development of skyscraper, earthquake-resistant structure becomes instantly popular topic, damper correlative study and answers
Good effect is achieved used in earthquake-resistant structure field, wherein what is be most widely used is exactly tuned mass damper and viscosity
Damper.But at the same time, traditional energy-dissipating and shock-absorbing component (such as viscous damper and tuned mass damper) is in structural damping
There are some deficiencies for being difficult to evade again, for example to be also easy to produce leakage, tuned mass damper damping frequency band narrow for damper with viscosity
Deng.Therefore, this project proposes a kind of floated bearing quality damper, i.e., liquid is immersed in cone mass block lower part, leads to simultaneously
Crossing deep groove ball bearing connection cone mass block pulls torsionspring to generate couple of force output damping.Project is in conventional tune Tuned mass damper
On the basis of device, liquid viscous damping and the spring torsion multiple damping mechanism of couple of force are introduced, mass tuning is further improved
The damping performance of damper has great practical meaning in engineering in earthquake-resistant structure.

Damper introduces liquid viscous damping and the spring torsion multiple damping of couple of force on the basis of conventional tune mass damper
Mechanism further improves the damping performance of tuned mass damper.
The utility model proposes a kind of floated bearing quality damper, including sunpender 1, deep groove ball bearing 2, torsion bullet
Spring 3, cone mass block 4, liquid 5 and steel cylinder 6, in which: liquid 5 is filled in steel cylinder 6,6 top of steel cylinder is fixed in 1 one end of sunpender
Lower section, the other end are connected with deep groove ball bearing 2, and torsionspring 3 is cased with outside deep groove ball bearing 2;4 top of cone mass block and torsion
Spring 3 consolidates, and lower part is suspended in liquid 5 by sunpender effect;4 side half portion of cone mass block is with ribbing, and aggravation fluid is viscid
Power uneven distribution.
In the utility model, 4 side half portion of cone mass block is with ribbing, passes through control cone half right and left and liquid contact surface
The different larger fluid viscous force uneven distributions of product improve cone degree of rotation to improve spring torsion couple of force.

Among liquid 5, increases and interact between cone mass block 4 and liquid 5, output damping.
In the utility model, torsionspring 3 uses plane scroll spring (such as clockwork spring), the spring material under torque effect
Material generates elasticity of flexure deformation, and spring is made planar to generate torsion, output damping.
Based on conventional tune mass damper, the utility model has the beneficial effects that:
(1) on the basis of remaining conventional tune mass damper, liquid viscous damping and spring twisting resistance are introduced
Coupling damping, realizes multiple damping mechanism.
(2) liquid viscous damping is introduced, the time lag for reducing conventional tune mass damper is conducive to, improves vibration early period
