Self-resetting friction-changing damper
The invention discloses a self-resetting friction-changing damper comprising a barrel, a baffle, a sliding shaft, an attachment joint, two fixed bases and a pair of damping mechanisms. The baffle is fixedly arranged in the barrel and provided with a through hole; the sliding shaft relatively slidingly penetrates through the through hole and a first end of the sliding shaft extends out of the barrel; the attachment joint is fixedly arranged at the first end of the sliding shaft; the two fixed bases are arranged on the bilateral sides of the baffle; each damping mechanism comprises an elastomer and a friction assembly, two ends of the elastomer are respectively abutted against the baffle and the friction assembly; the friction assembly comprises two extruding wedges and a plurality of friction wedges, the mutual opposite surfaces of the extruding wedges are circular cone guiding surfaces, and the friction wedges can be slidingly and circumferentially arranged between the circular cone guide surfaces of the two extruding wedges at intervals. By the self-resetting friction-changing damper, friction can be self adjusted according to the major structure displacement response, and a plurality of hysteretic curves can be displayed by adjusting parameters, and the self-resetting friction-changing damper has the function of self-resetting and strong engineering applicability.
