Abstract

Provided is a self-resetting wane type friction composite damper. Two bolt groove hole slide ways (2') penetrating through an outer pipe (2) are formed in the outer pipe (2), the length of the bolt groove hole slide ways is equal to that of a bolt groove hole slide way (1'), and a connecting key is arranged at the left end of the outer pipe (2). Sliding bolt assemblies (3) are mounted in the bolt groove hole slide way (1') and the bolt groove hole slide ways (2') and are in clearance fit with the outer pipe (2); an elastomer (4) is arranged in an inner pipe (1), hooks are arranged at the two ends of the elastomer (4) and hung on limiting bolts of the sliding bolt assemblies (3) respectively, and the inner pipe (1) and the outer pipe (2) are closely connected together. A friction viscoelasticity assembly (5) is connected to the inner wall of the outer pip (2) through bolts (8); a fixed hinge support assembly (6) is mounted on the outer wall of the inner pipe (1), and a friction wane (9) is mounted on the fixed hinge support assembly (6).

Description

technical field [0001] The invention relates to a novel energy-dissipating support damper technology, in particular to a damper control technology with variable friction and self-resetting functions. Background technique [0002] Chinese patent CN 104482093 A discloses a self-resetting variable friction damper, such as figure 1 As shown, the technical content is as follows: [0003] When the self-resetting variable friction damper is in the initial equilibrium position, the elastic bodies 6 on both sides of the baffle plate 5 are of natural length, that is, the precompression amount is zero. At this time, the two ends of the elastic body are just in contact with the baffle plate 5 and the extrusion wedge 7 respectively, and the pressure on the contact surface is zero, and the extrusion wedge 7 and the friction wedge 8, as well as the friction wedge 8 and the inner wall of the cylinder 1 They are also just in contact with each other. When the sliding shaft 2 moves relative...
