Description

Solid medium damper

Technical Field

The utility model relates to a solid medium attenuator belongs to shock attenuation technical field.

Background

The structure damping passive control technology has the obvious advantage of reducing the damage effect of earthquake energy on structures, has better application prospect in the field of civil engineering earthquake resistance, and is widely concerned by the engineering field. Among them, viscous dampers have been widely used in many projects. The traditional viscous damper has the characteristics of low rigidity and high damping, and the damping mechanism is to dissipate the energy entering the structure through the viscous characteristic and the hole shrinkage effect of a damping medium, so that the aims of reducing the structural vibration and protecting the safety of a main body structure are fulfilled. However, the viscous damper in the prior art mainly uses silicon oil as a damping medium, which not only has high requirements on sealing, but also inevitably causes silicon oil leakage in a standing state and a use process, so that the energy consumption effect of the damper is weakened, and even the damper fails.

Disclosure of Invention

For overcoming the defects of the prior viscous damper, the utility model aims to solve the problem of providing a solid medium damper.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a solid medium attenuator, including the cylinder body of taking the cavity, set up the piston in the cylinder body cavity, its characterized in that the piston both ends are equipped with rather than even left and right guide arm as an organic whole, be equipped with corresponding left and right end cap through wear-resisting ring on the left and right guide arm, and form left and right cavity between left and right end cap and the piston end that corresponds, left and right cavity intussuseption is filled with solid damping medium, and left and right cavity communicates each other through the clearance between piston and the cylinder body, make the solid damping medium in left and right cavity can the mutual displacement under the atress condition, be used for energy in the dissipation entering structure, reduce the structural vibration, when protecting the major structure safety, can not leak solid medium.

The left end of the piston guide rod is connected with the left connector, the right end of the piston guide rod is arranged in the cavity of the right connector, and the left connector and the right connector are respectively connected with a connecting member on a building through bearings.

And the wear-resistant parts between the left and right plugs and the guide rod are conventional products.

The solid damping medium is a flexible material taking rubber as a matrix and is made into one or more of particles, sheets, strips and blocks.

The utility model has the advantages of it is following and effect: by adopting the scheme, the solid media in the left cavity and the right cavity can move mutually under the stress condition conveniently, so that the problems of silicone oil leakage and damper failure caused by vibration reduction of silicone oil in the prior art are solved fundamentally while energy entering the structure is dissipated, structural vibration is reduced and the safety of the main body structure is protected, the stability of the damper is improved, and the service life is prolonged. The obtained solid medium selects a viscoelastic material as a base material, is coordinated and matched with a heat radiating agent, an energy dissipating agent, a modulus regulator and an antioxidant in a specific ratio, and adopts a special preparation process, so that the solid medium has the advantages of good damping performance, lower temperature sensitivity and the like, the sealing requirement is greatly reduced, the damper structure is simpler and more reliable than the existing structure, and the manufacturing difficulty and the cost are greatly reduced.
