Problems solved by technology

In this way, there are disadvantages such as large local bending stress at the connecting end of the damping outer cylinder, uneven compressive stress of the friction material, and excessive compressive stress near the lug plate.
On the one hand, it makes the design of the damping outer cylinder more difficult; on the other hand, from the perspective of friction performance, it not only reduces the friction efficiency and stability of the friction material, but also reduces the durability of the friction material due to the high local stress of the friction material

Embodiment Construction

[0033] In order to facilitate the understanding of the structure of the present invention, the following description will be made in conjunction with the accompanying drawings and embodiments.

[0034] see figure 1 and figure 2 , figure 1 A schematic structural view of the cylindrical friction damper of the present invention is shown; figure 2 shown figure 1 Sectional view of A-A in the middle. The cylindrical friction damper of the invention provides a friction damping force along the friction direction. Realize by constraining the frictional force generated by the relative displacement between the inner cylinder 8 and the outer cylinder 3 of the hoop. The hoop outer cylinder 3; and the first connection device and the second connection device respectively connected to the constraint inner cylinder 8 and the hoop outer cylinder 3, and connected to the first main body component and the second main body component. Wherein, the knot-drawing device includes a first clampin...

Abstract

The invention provides a cylindrical friction damper and a loading method thereof. The cylindrical friction damper comprises a constraint inner cylinder, a hoop outer cylinder and a tensioning device, wherein the constraint inner cylinder is connected with a first main body structure; the hoop outer cylinder is connected with a second main body structure, and comprises a first hoop body and a second hoop body outside the constraint inner cylinder; and the tensioning device comprises a first clamping piece arranged outside the first hoop body, a second clamping piece arranged outside the second hoop body, and a fastening piece fixed between the first clamping piece and the second clamping piece. A friction damping layer is hooped by the hoop outer cylinder, and force is uniformly applied to the hoop outer cylinder via the first clamping piece and the second clamping piece, so that the force of the fastening piece is relatively uniformly transferred to the end of the hoop outer cylinder and the friction damping layer; the cylindrical friction damper is simple in structure, convenient in material acquisition, high in frictional efficiency and strong in stability and durability.

Description

technical field [0001] The invention relates to the field of building construction tools, in particular to a cylindrical friction damper and a loading method thereof. Background technique [0002] Friction damper is a kind of control device that utilizes the frictional energy consumption of friction surface to dissipate vibration energy. It has simple structure, convenient installation, good energy consumption, and its performance is not affected by temperature. Can shock absorber. Traditional friction dampers include cylinder type, plate type, spring type and so on. According to the theory of tribology, the friction coefficient is closely related to the pressure and the actual friction area. For the cylindrical friction damper, the outer fixing device for fixing the damping outer cylinder and the damping layer generally adopts the hoop type. The connecting ends of the two semicircular damping outer cylinders are connected by an external ear plate (similar to a traditiona...
