Embodiment Construction

[0010] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] From attached figure 1 It can be seen that the present invention relates to a viscous damping limiting method for a viscous damper with a limiting device, including a conventional viscous damper, on one side of the conventional viscous damper, a left earring and a right earring A limit device is set between them, and the viscous damper is limited when the static load deformation of the viscous damper exceeds the design stroke through the limit device. The limiting device is an elastic rubber block structure, which is connected with a piston rod of the viscous damper, and can be compressed by the elastic rubber block when the static load deformation of the viscous damper exceeds the design stroke. Act as a limiter.

[0012] In the present invention, within the design stroke of the viscous damper, only the conventional vi...

Abstract

The invention discloses a viscous damping limiting method with a limiting device; the limiting device is arranged between a left ear ring and a right ear ring at one side of a conventional viscous damper; the viscous damper is limited through the limiting device when the static load deformation thereof exceeds the design stroke; the limiting device is in an elastic rubber block structure; and the elastic rubber block structure is connected with a piston rod at one end of the viscous damper, and performs the limiting function through the compression of the elastic rubber block when the static load deformation of the viscous damper exceeds the design stroke. The invention has the effects of improving the dynamic response to the structure and generating the limit resistance to the excessive displacement of the structure. Compared with the prior art, the invention has simple structure, and saves cost and installation space.

Description

technical field [0001] The invention relates to an elastic vibration damping element, in particular to a viscous damper with a limit device inside. The limit device is used to provide the axial static limit force of the viscous damper, and belongs to the technical field of vibration reduction and shock resistance . Background technique [0002] The viscous damper is a non-stiffness, speed-dependent damper, which is mainly used in large and high-rise building structures such as bridges, houses, and industrial buildings to dissipate destructive energy caused by earthquakes and strong winds. Because the damping force of the viscous damper is determined by the speed, it is not sensitive to the low-speed static load caused by temperature changes, automobile braking, etc., and has no damping effect on the structural deformation caused by it. If the structural deformation exceeds the design displacement, the structure may be damaged. [0003] The existing limit technology of visc...
