Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1-4 As shown, a viscoelastic shear friction damper includes an outer guide sleeve and an inner guide sleeve. The inner end of the inner guide sleeve is sleeved in the outer guide sleeve and can move axially relative to the outer guide sleeve. The inner end of the inner guide sleeve The central part is provided with a pressure bolt along the axial direction, and the pressure bolt is fixedly connected with the inner guide sleeve. Several damping parts are set on the pressure bolt. The force transmission steel plate, the spring is arranged between the adjacent damping parts, and the spring is set on the pressure bolt, and the pressure nut is set on the pressure bolt, which is matched with its thread, and the innermost damping part is against the inner guide sleeve. end, the outermost damping element is against the compressi...

Abstract

The invention relates to a viscoelastic shearing friction damper and an application method. The viscoelastic shearing friction damper comprises an outer guide sleeve and an inner guide sleeve, whereinthe inner end of the inner guide sleeve is sleeved in the outer guide sleeve; a compression bolt is arranged axially at the middle part of the inner end of the inner guide sleeve; the compression bolt is fixedly connected with the inner guide sleeve; a plurality of damping parts are sleeved on the compression bolt; each damping part comprises a viscoelastic bulk and force transfer steel plates arranged at the two ends of the viscoelastic bulk; a spring is arranged between adjacent damping parts; the spring is sleeved on the compression bolt; the compression bolt is sleeved with a compressionnut in screw thread fit with the compression bolt; the damping part on the innermost side is placed against the inner end of the guide sleeve; the damping part on the outermost side is placed againstthe compression nut; all damping parts are fixed on the compression bolts through the compression nuts. The damping force of the damper is adjustable; by organically combining the shearing energy consumption with speed displacement type sliding energy consumption, the energy consumption effect is good.

Description

technical field [0001] The invention relates to a viscoelastic shear friction damper and a using method. Background technique [0002] A viscoelastic damper is a viscous damping device with stiffness. The existing damper has only one energy dissipation mechanism, which does not organically combine the shear energy dissipation and the velocity-displacement sliding energy dissipation, and the energy dissipation effect is poor. At the same time, the existing damper cannot adjust the damping force. Can not meet the needs of use. Contents of the invention [0003] The invention provides a viscoelastic shear friction damper and a use method thereof. [0004] The solution adopted by the present invention to solve the technical problem is that a viscoelastic shear friction damper includes an outer guide sleeve and an inner guide sleeve, the inner end of the inner guide sleeve is set inside the outer guide sleeve, and the middle part of the inner end of the inner guide sleeve is...
