Background technique
Thereby utilize attached member such as damping device to carry out energy-dissipating and shock-absorbing at present and guarantee that the method for agent structure Security under earthquake or wind such as shake at dynamic load function is in the ascendant.The use of granule damper does not receive temperature limitation basically; The location arrangements of granule damper is flexible, in vibration control, has good damping effect and development prospect.Its basic principle is: when structural vibration, utilize between the particle and particle and cavity wall between friction, energy dissipation is carried out in collision and dress changes, thereby reduce structural vibrations.
At the beginning of the eighties in last century, Popplewell etc. have invented flexible particle damping, with certain particle of flexible material parcel some and with it as in the structural cavities.The utility application (patent No. is 201020241597.6) of " a kind of flexible granule damper " of State Intellectual Property Office's notice of authorization, this damper comprise flexible material packaging body of processing and the particulate matter that is wrapped in the packaging body; Packaging body is to have the shoestring of cavity or have the tabular body of the cavity that a plurality of one-tenth faces arrange or have a plurality of blocks that become the three-dimensional cavity of arranging.Then State Intellectual Property Office's notice of authorization the utility application (patent No. is 201120051956.6) of " a kind of granule damper elementary cell and relevant granule damper "; This model utility provides a kind of granule damper elementary cell, includes the shell and the interior particulate matter of the cavity that is packaged in shell of cavity; The utility model also provides a kind of granule damper simultaneously, comprises the particulate matter in packaging body with cavity and the said cavity that is packaged in the said packaging body.
With regard to above-mentioned granule damper; The intergranular relative movement of damping is limited; Between the particle or the damping that produces of the frictional impact between particle and the cavity wall limited, the energy-dissipating and shock-absorbing effect also just is difficult to meet the demands, thereby increases the damping of granule damper; Improve the damping effect of granule damper, the development that promotes granule damper is had important effect in building structure.
Summary of the invention
Based on the problems referred to above, for increasing the damping of existing granule damper, the utility model proposes a kind of nesting type granule damper, and its design proposal is following:
A kind of nesting type granule damper includes shell 1, resisting medium 2, internal particle 3, particle 4, casing 5; Internal particle 3 places shell 1 inside, in the cavity that internal particle 3 and shell 1 are formed, fills resisting medium 2; Shell 1, resisting medium 2 and internal particle 3 are formed particle 4; Particle 4 places casing 5 or places each cavity of cellular structure.
The material of described resisting medium 2 is a silicone oil.
The material of shell 1 is flexible material or elastic material; Described flexible material comprises rubber, plastics; Described elastic material comprises steel.
Described internal particle 3 is metallic material or nonmetallic material, and described metallic material comprises steel, lead, iron, aluminium, and described nonmetallic material comprise glass bead, stone.
Described casing 5 is connected with existing structure through bolt 6.
The quantity of the internal particle 3 in described each shell 1 is one or more than one, and is not limited only to one.
The utility model is filled resisting medium in container, introduced intergranular viscous resistance, and the damping of granule damper makes particle itself have the power consumption effect when having increased vibration.That this kind damping particle is made is simple and convenient, be prone to assembling, and this granule damper can directly be connected with member as damper separately simultaneously, also can be used as a kind of damping particle elementary cell, is used for consuming energy among placing casing or member.
