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 technique
Tuned mass damper is a kind of vibration damping equipment being widely adopted in recent years, and it is comprised of mass block, spring and damped system.The natural frequency of vibration and main structure by damping adjusting device approach, thereby reach and mesomerism vibration damping.Existing tuned mass damper is the translation vibration characteristics for structure mostly, weakens structure level direction and vertical motion, is seldom useful on the damper that weakens construction torsion.But find in engineering, a lot of long fine textures, such as pedestrian overpass, vestibule or chimney, tall and slender structure etc. reverse the vibration shape, can occur too early, in using process, be subject to wind load or unbalanced Pedestrian Load etc. can cause torsion acceleration excessive, affect comfort level or even Security.The present invention is the damper for the situation of torsion, utilizes the frequency of spring damping adjusting device, utilizes the collision between particle swarm to increase energy consumption.And easy for installation, do not affect the use function of structure.
Summary of the invention
Object of the present invention is exactly that a kind of torsional frequency of tuning long fine texture is provided in order to overcome the defect of above-mentioned prior art existence, thereby weakens structure around the torsion of long axis direction, and guarantees the tuning granule damper of the anti-longitudinal axis torsion of use complete function.
Object of the present invention can be achieved through the following technical solutions:
The tuning granule damper that the anti-longitudinal axis reverses, comprising:
The concrete main body plate that offers plate hole, offers toroidal cavity in the periphery in plate hole;
In described toroidal cavity, be provided with the damping assembly being formed by spring and particle swarm,
The upper and lower surface of concrete main body plate is provided with concrete cover makes toroidal cavity form enclosed space.
As preferred embodiment, the two ends in toroidal cavity arrange spring, between two springs, particle swarm are set.Wherein, the rigidity of spring is according to being determined by the torsional frequency of control structure.The number of turns that increases and decreases spring by adjusting regulates rigidity.Particle swarm is several steel balls or concrete ball.
As the mode of execution being more preferably, the alloy helical spring that spring is 50CrVA.The quantity of steel ball or concrete ball and size require to determine according to the vibration damping of damper.
Toroidal cavity is provided with four, is the periphery that segmentation structure is evenly distributed on plate hole.
The size of described concrete main body plate according to the cross section of long fine texture require to be square, circular or special-shaped.
The bight of described concrete main body plate is also provided with the angle steel being connected with agent structure.
Compared with prior art, the present invention has the following advantages:
(1) adopt concrete to make the material of agent structure and particle, can greatly reduce apparatus cost.
(2) effect of playing tuned mass damper medi-spring and mass block by the spring installed in toroidal cavity and particle swarm.The consumed energies such as acoustic radiating, frictional heat energy or plastic deformation that produce by the collision between particle swarm, play the effect of viscous damper in tuned mass damper.
(3), by the acting in conjunction of four cavity inner springs and particle swarm, final realization with tuning by the torsional frequency of control structure, plays the effect that weakens torsional vibration.
(4) each several part collaborative work, fabrication and installation are simple, and cost performance is higher, does not affect construction and uses function.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
The tuning granule damper that the anti-longitudinal axis reverses, as shown in Figure 1-2, the mechanisms such as damping assembly that this damper is mainly comprised of concrete main body plate 1, spring 3 and particle swarm 4 form its structure.
The size of concrete main body plate 1 requires to do squarely, circle or special-shaped according to the cross section of long fine texture, and the angle steel 6 by bight is connected with agent structure.Central authorities at concrete main body plate 1 also offer plate hole 8, facilitate workman or construction plant to pass through.In the periphery in plate hole 8, offer toroidal cavity 2, in the present embodiment, toroidal cavity 2 is provided with four, is the periphery that segmentation structure is evenly distributed on plate hole 8.
Two ends in toroidal cavity 2 arrange between 3, two springs 3 of spring particle swarm 4 are set.Wherein, the rigidity of spring 3, according to being determined by the torsional frequency of control structure, can regulate rigidity by the number of turns of increase and decrease spring 3.In the present embodiment, the alloy helical spring that the spring 3 of use is 50CrVA.Particle swarm 4 is several steel balls or concrete ball, and quantity and size require to determine according to the vibration damping of damper.In addition, in concrete main body plate 1 both sides, concrete cover 5 is installed, its structure as shown in Figure 3,4, matches with concrete main body plate 1.Concrete cover 5 is arranged on the upper and lower surface of concrete main body plate 1 by cover plate construction bolt 7, make toroidal cavity 2 form enclosed space.
This invention completes the concrete moulding of building in factory according to figure paper size, for avoiding producing larger vibration, at the scene Installation and Debugging in transportation process.Concrete main body plate 1 by angle steel 6 with by control structure, be connected and fixed.At the scene in debug process, increase or reduce the frequency that the number of turns of spring 3 can damping adjusting device, thus with reality by control structure frequency modulation.After debugging finishes, concrete cover 5 and concrete main body plate 1 is fixing by cover plate construction bolt 7.So can realize similar to the tuned mass damper torsion proof function of supporting.
