Description
Technical field
The present invention relates to a kind of damper, especially relate to the tuning granule damper that a kind of anti-longitudinal axis reverses.
Background technology
Tuned mass damper is a kind of vibration absorber being widely adopted in recent years, and it is by mass, spring and resistance
Damping system forms.Close with main structure by the natural frequency of vibration of damping adjusting device, reach and mesomerism thus vibration damping.
Existing tuned mass damper is the translation vibration characteristics for structure mostly, i.e. weakens structure level direction and erects
To vibration, rarely useful in the damper weakening construction torsion.But engineering finds, a lot of long fine textures, than
As overpass, vestibule or the torsion vibration mode such as chimney, tall and slender structure can occur too early, wind-engaging lotus during use
Carry or unbalanced Pedestrian Load etc. can cause torsion acceleration excessive, affects comfort level even security.This
Invention be i.e. for reverse situation damper, utilize the frequency of spring damping adjusting device, utilize particle swarm it
Between collision increase energy ezpenditure.And easy for installation, do not affect the use function of structure.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of tuning long thin knot
The torsional frequency of structure, thus weaken the structure torsion around long axis direction, and ensure to use the anti-twisting longitudinal axis of complete function
The tuning granule damper turned.
The purpose of the present invention can be achieved through the following technical solutions:
The tuning granule damper that a kind of anti-longitudinal axis reverses, including:
Offer the concrete main body plate in plate hole, offer toroidal cavity in the periphery in plate hole；
The damping assembly being made up of spring and particle swarm it is provided with in described toroidal cavity,
The upper and lower surface of concrete main body plate is provided with concrete cover makes toroidal cavity form closing space.
As preferred embodiment, the two ends in toroidal cavity arrange spring, arrange particle swarm between two springs.
Wherein, the rigidity of spring determines according to the torsional frequency of controlled structure.By the number of turns regulation of regulation increase and decrease spring just
Degree.Particle swarm is several steel ball or concrete ball.
As embodiment more preferably, spring is the alloy helical spring of 50CrVA.Steel ball or concrete ball
Quantity and size determine according to the damping requirements of damper.
Toroidal cavity is provided with four, is evenly distributed on the periphery in plate hole in segmentation structure.
The size of described concrete main body plate requires to be square according to the cross section of long fine texture, circular or special-shaped.
The corner of described concrete main body plate is additionally provided with the angle steel being connected with agent structure.
Compared with prior art, the invention have the advantages that
(1) use concrete to make the material of agent structure and particle, apparatus cost can be substantially reduced.
(2) spring and particle swarm by installing in toroidal cavity play spring and quality in tuned mass damper
The effect of block.Disappeared by the acoustic radiating, the frictional heat energy that collide generation between particle swarm or be plastically deformed etc.
Energy consumption, plays the effect of viscous damper in tuned mass damper.
(3) by four cavity inner springs and the common effect of particle swarm, the final torsion realized with controlled structure
Frequency tuning, plays the effect weakening twisting vibration.
(4) each several part collaborative work, fabrication and installation are simple, and cost performance is higher, do not affect construction and use function.

Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
The tuning granule damper that a kind of anti-longitudinal axis reverses, as shown in Figure 1-2, this damper is mainly by mixing for its structure
Mechanism's compositions such as the damping assembly of solidifying soil main board 1, spring 3 and particle swarm 4 composition.
The size of concrete main body plate 1 requires to do squarely, circular or different according to the cross section of long fine texture
Shape, is connected with agent structure by the angle steel 6 in corner.Central authorities at concrete main body plate 1 are further opened with plate hole 8,
Workman or construction machinery is facilitated to pass through.Toroidal cavity 2, in the present embodiment, ring is offered in the periphery in plate hole 8
Shape cavity 2 is provided with four, is evenly distributed on the periphery in plate hole 8 in segmentation structure.
Two ends in toroidal cavity 2 arrange spring 3, arrange particle swarm 4 between two springs 3.Wherein, spring
The rigidity of 3 determines according to the torsional frequency of controlled structure, can be by the number of turns regulation rigidity of increase and decrease spring 3.This
In embodiment, the spring 3 of use is the alloy helical spring of 50CrVA.Particle swarm 4 is several steel ball or coagulation
Soil ball, quantity and size determine according to the damping requirements of damper.It addition, install in concrete main body plate 1 both sides
Concrete cover 5, its structure as shown in Figure 3,4, matches with concrete main body plate 1.Concrete cover 5
By cover plate, bolt 7 is installed and is arranged on the upper and lower surface of concrete main body plate 1, make toroidal cavity 2 be formed and close sky
Between.
This invention pours shaping, for avoiding producing relatively in transportation in factory according to what figure paper size completed concrete
Big vibration, can installation and debugging at the scene.Concrete main body plate 1 is connected fixing by angle steel 6 with controlled structure.
At the scene debugging during, increase or reduce spring 3 the number of turns can with the frequency of damping adjusting device, thus with reality
Border controlled structure frequency modulation.After debugging terminates, concrete cover 5 and concrete main body plate 1 are installed spiral shell by cover plate
Bolt 7 is fixed.So can realize similar to tuned mass damper to torsion proof function.
