Abstract
The utility model relates to a partition type lamination particle damper which belongs to the field of vibration control and comprises box bodies (1) with flanges, particles (2), transverse partition plates (3), longitudinal partition plates (4) and bolts (5). Each box body (1) with the flange are divided into four or more than four even spaces by the horizontal partition plates (3) and the longitudinal partition plates (4) in the horizontal plane, particles (2) are evenly arranged in the spaces formed by the box bodies (1), the horizontal partition plates (3) and the longitudinal partition plates (4), and all box bodies with flanges are connected through connection members (5). The box bodies are divided into a plurality of spaces, one layer of damping particles is arranged in each box body, and a plurality of box bodies are connected to form the partition type lamination particle damper. Thus, the particle extrusion problem caused by accumulation of damping particles is solved, and damping effect of the damper can be effectively improved.
Description
Technical field:
The utility model relates to a kind of granule damper, and particularly partition type lamination granule damper belongs to the vibration control field, can be used for the damping control in fields such as machinery, Aero-Space and building structure.
Background technique:
Under dynamic load function, the damping particle will have that rolling, slip, colony are flowed and characteristic such as friction.Granule damper is a kind ofly to realize distributed damping, have tuning and the comprehensive damper power consumption function; When vibration takes place; Utilize between the particle and particle and cavity wall between friction, collision carry out energy dissipation and conversion, thereby reduce structural vibrations.The use of granule damper does not receive temperature limitation basically, and location arrangements is flexible, in the vibration control field, has bright development prospect.
Granule damper mainly comprises at present: and nonobstructive particle damping NOPD, band piston vibration particle damping PTD and flexible particle damping (the steamed buns stuffed with sweetened bean paste particle, BBD).The application for a patent for invention (patent No. 200910087710.1) of a kind of " built-in particle type tuning and frictional impact energy-consumption damper " that State Intellectual Property Office has been authorized; As shown in Figure 1; This damper comprises: the casing 6 that is connected with building structure floor member or beam column member, be placed in damping particle swarm 7, box house dividing plate 8 and connector element 5 in the casing; Damping particle swarm 7 is deposited in casing 6, internal partition 8 and building structure floor member or the formed space of beam column member uniformly; Utilize between the particle and particle and cavity wall between friction, collision carry out energy dissipation and conversion; But, reduced the damping effect of particle damping to a certain extent because the mutual accumulation of particle causes the problem that has mutual extrusion between the particle.
Summary of the invention:
In order to solve the problem of mutual extrusion between the particle that exists in the existing granule damper, the utility model provides a kind of partition type lamination granule damper.
For realizing above-mentioned purpose, the design proposal of the utility model is following:
Partition type lamination granule damper includes casing 1, particle 2, lateral partitions 3, longitudinal baffle 4, the bolt 5 of being with the edge of a wing; It is characterized in that: lateral partitions 3 and longitudinal baffle 4 will evenly be separated into four or more homogeneous space with the casing 1 on the edge of a wing in horizontal plane; Particle 2 evenly is placed in the space of casing 1, lateral partitions 3 and longitudinal baffle 4 formation; Connect through connector element 5 between the casing 1 on each band edge of a wing.
The height in casing 1 space on the described band edge of a wing is for only placing one deck particle; The casing 1 on the band edge of a wing connects in short transverse.
Described particle 2 is shaped as sphere or elliposoidal or cuboid shape or space polyhedron shape, and its material is steel.
Casing 1 is connected with the existed building structure through connector element 5.
Described connector element 5 is a bolt.
The casing 1 on the band edge of a wing the number of plies of short transverse be two-layer or two-layer more than.
The utility model is divided into a plurality of spaces with increasing internal partition (lateral partitions 3 and longitudinal baffle 4) in the casing of existing built-in particle type tuning and frictional impact energy-consumption damper; Place one deck damping particle in each casing; The partition type lamination granule damper that utilizes bolt that a plurality of casings are connected to form; Solve the particle extruding problem that the intergranular accumulation of damping causes, can effectively improve the damping effect of this damper.

Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Like Fig. 2, Fig. 3 and partition type lamination granule damper shown in Figure 4, include casing 1, particle 2, lateral partitions 3, longitudinal baffle 4, the bolt 5 on the band edge of a wing; Lateral partitions 3 will evenly be separated into four spaces with the casing 1 on the edge of a wing with longitudinal baffle 4; Particle 2 evenly is placed in the space of casing 1, lateral partitions 3 and longitudinal baffle 4 formation, guarantees to have uniform gap between particle, avoid can't moving because of all particle aggregations cause particle, thus forfeiture power consumption effect; The height in casing 1 space on the band edge of a wing avoids damper to lose efficacy because of the accumulation of particle for only placing one deck particle; The shape sphere of particle 2 or elliposoidal or cuboid shape or space polyhedron shape, the material of particle 2 are steel, and its diameter is slightly less than the height in space in the casing; Casing, lateral partitions and longitudinal baffle all adopt steel; The casing 1 on two band edges of a wing is through bolt 5 stacks; Casing 1 is connected with the existed building structure through bolt 5.
The number of above-mentioned casing can and abovely be not limited only to two for two, and every layer subregion can be for being not limited only to four more than four and four.
