Description

[0001] COIL SPRING DMAPER CYLINDER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil spring damper cylinder, and more particularly, to a cylinder having an elastic spring and an elastic body for suppressing relative displacement and improving damping performance in vibration due to an earthquake.

The structure should be designed to withstand the seismic loads due to the full elastic behavior or the elasticity due to inelastic behavior up to the required level of elasticity in the load displacement relationship. An effective method to improve the seismic performance of a structure can be to examine the seismic or damping structure.

The vibration suppression device is installed in a place where the displacement of the structure is largely generated, and is used for reducing deformation generated in the structure by increasing damping and action of dissipating the energy by deformation. The seismic isolation system is used for the purpose of reducing response by lengthening the period of the structure by reducing the response such as displacement and acceleration of the structure.

Unlike seismic isolation devices, vibration suppression devices not only show vibration reduction effects in independent equipment and facilities but also have sufficient effects in high-rise structures and contribute to improvement in habitation.

Prior art 1 (Korean Patent No. 10-1093474) is a vibration damper having a damping force according to an amplitude. However, the prior art 1 has a problem that the structure of the piston rod is complicated and the number of parts is increased, while the stroke of the piston rod is advantageously made as large as possible.

Prior Art Document 2 (Korean Patent No. 10-1398365) is a friction type energy dissipating device using a disk spring that includes a compression spring and a tension spring inside a cylinder to absorb and dissipate vibration energy corresponding to compression or tension . However, the prior art 2 has no knowledge about the plastic deformation of the spring, and thus the hysteretic energy dissipating ability of the steel can not be expected.

As described above, according to the present invention, it is possible to restore the elastically deformed carbon spring after the energy dissipation function by utilizing the hysteretic energy dissipation function and the elasticity of the elastic body, which are exhibited by plastic deformation of the elastic spring.

Further, by the fixing means formed to protrude into the inside of the cylinder, the elastoplastic spring can be fixed to the cylinder with a simple structure, and the spring or the elastic body can be easily damaged by the breakage or replacement by the life.
