Three-dimensional amplifying viscous damper

Abstract

The invention discloses a three-dimensional amplifying viscous damper, which comprises a containing cavity, a swing piece, a first connecting piece and a second connecting piece. The first connectingpiece and the swing piece are movably connected, and the second connecting piece is connected with a spherical bulge on the swing piece to form a spherical pair; the first connecting piece and the second connecting piece are provided with an upward-extending second fixing assembly and a downward-extending seconding fixing assembly correspondingly; a damping agent is arranged in the containing cavity, and the lower end of the swing piece is provided with a plate structure with a plurality of hole grooves; a flow blocking assembly stretches into the damping agent through an opening in the upperend of the containing cavity; and the plane projection of the flow blocking assembly is a circle or a rotationally symmetric figure with the rotating angle being a, wherein the rotating angle a is smaller than 90 degrees. During moving of the flow blocking assembly, the side faces are hindered by the damping agent, thus the damping agent forms a large buffering effect when penetrating through thegroove holes in the flow blocking assembly, and the damping effect of the flow blocking assembly in multiple directions can be achieve. The three-dimensional amplifying viscous damper is used for thefield of construction engineering.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a three-dimensional enlarged viscous damper. Background technique [0002] A damper is a device used to provide movement resistance and consume movement energy. In industries such as aerospace, aviation, military industry, guns, and automobiles, various dampers are used for shock absorption and energy dissipation to make their operations safer and more stable. Since the 1970s, people have gradually transferred these technologies to structural engineering such as buildings, bridges, and railways, and their development has been very rapid. Especially in the past 20 to 30 years, people have made great efforts to improve the anti-vibration ability of buildings by using dampers, and have jumped out of the traditional concept of strengthening beams, columns, and walls to improve anti-vibration ability. Performance, skillfully avoid or reduce the damage of earthquake and wind. ...

AI Technical Summary

Problems solved by technology

There are some dampers on the market for shock absorption and energy dissipation in the horizontal direction, but most of them can only achieve shock absorption and energy dissipation at two orthogonal angles in the horizontal direction, which has relatively large limitations
