High-performance composite friction damper
The invention discloses a high-performance composite friction damper, which relates to the technical field of dampers and comprises a connecting assembly, a friction assembly, a fastening assembly and a limiting assembly, the connecting assembly comprises an outer connecting piece, an inner connecting piece and a viscoelastic damping piece; a friction part is arranged on the end surface of the inner connecting piece; the friction assembly comprises a friction core plate, and the friction core plate is in contact connection with the friction part. The fastening assembly comprises a fastening piece and a locking piece; the limiting assembly comprises a first limiting part and a second limiting part; when the earthquake displacement is smaller than the distance between the limiting block and the friction core plate, the first-order viscoelastic energy consumption unit consumes energy and outputs first-order damping force; when earthquake displacement is larger than the distance between the first limiting part and the friction core plate, the outer connecting piece drives the friction core plate to slide, the viscoelastic energy dissipation unit and the friction energy dissipation unit work together, second-order damping force is output, the energy dissipation requirements in different scenes are met, the damping force is gradually increased along with displacement increase, and the energy dissipation and shock absorption effect is obvious.
