Composite damper
The invention discloses a composite damper, and relates to the technical field of anti-seismic instruments. The composite damper comprises two inner connecting pieces, two outer connecting pieces anda plurality of deformable energy dissipation components; the two inner connecting pieces are rotationally connected with each other; the included angle between the two inner connecting pieces is a when the two inner connecting pieces are not subjected to external force, and a is larger than 0 degree and smaller than 180 degrees; one ends of the two outer connecting pieces are rotationally connected to the two inner connecting pieces respectively; the ends, not connected to the inner connecting pieces, of the two outer connecting pieces are used for being connected with an external to-be-dampedcomponent; two ends of each deformable energy dissipation component are connected to the two inner connecting pieces respectively; a mechanism formed by hinging the two inner connecting pieces can serve as a displacement amplifying mechanism of the deformable energy dissipation components; and friction can be generated when the outer connecting pieces rotate relative to the inner connecting pieces and the two inner connecting pieces rotate relative to each other. The composite damper comprehensively utilizes two energy dissipation mechanisms of metal yield and friction, has a displacement amplification function, and greatly improves the damping effect.
本发明公开了一种复合型阻尼器，涉及抗震仪器技术领域，包括：两个内连接件、两个外连接件和若干个可变形耗能构件；两个内连接件相互转动连接，且不受外力时两个内连接件之间的夹角为a，0°
