Composite metal damper
The invention discloses a composite metal damper. The composite metal damper comprises two connecting end plates extending in the axial direction and further comprises an energy dissipation core plate, a first middle plate, a second middle plate, a friction plate and outer side constraint plates, wherein the energy dissipation core plate is arranged between the two connecting end plates and extends in the radial direction. The metal damper and a friction damper are ingeniously combined, the outer side constraint plates of the friction damper are used as constraint components of the energy dissipation core plate of the metal damper, the outer side constraint plates on the two sides are pre-tightened through bolts, out-of-plane deformation of the energy dissipation core plate is restrained,the performance of the metal damper is enhanced, and the damage to the energy dissipation core plate caused by the traditional mode of welding stiffening ribs is avoided; and by utilizing the hysteretic characteristic of the friction damper, the second rigidity of the metal damper is effectively reduced, so that the metal damper meets the requirement of anti-seismic design.
本发明公开了一种复合型金属阻尼器，包括轴向延伸的两个连接端板；还包括设于两个连接端板之间径向延伸的耗能芯板、第一中间板、第二中间板、摩擦板以及外侧约束板；通过将金属阻尼器与摩擦阻尼器巧妙结合，利用摩擦阻尼器的外侧约束板作为金属阻尼器耗能芯板的约束构件，两边的外侧约束板通过螺栓预紧，约束耗能芯板的面外变形，既增强了金属阻尼器的性能，又避免了传统焊接加劲肋的方式对耗能芯板的损伤；利用摩擦阻尼器的滞回特性，有效的减少了金属阻尼器的第二刚度，使得金属阻尼器能够满足抗震设计的需求。
