Composite damper
The invention discloses a composite damper, and belongs to the technical field of structural damping. The main body comprises a friction damping unit, a viscoelastic damping unit and a connecting unit. Through series connection of the friction damper and the viscoelastic damper, the two dampers can complement each other, and structural vibration generated by wind vibration and earthquakes can be effectively reduced. The viscoelastic body firstly deforms in micro-vibration (such as wind vibration) and small and medium-sized earthquakes, and when the vibration amplitude is increased, the viscoelastic damping unit is locked, so that the friction damping unit is forced to consume energy through friction, and vibration is reduced. Therefore, due to the fact that two damping functions are combined on one damper, a larger degree of freedom is provided on building planning, and the cost of the damping system is also remarkably reduced. In addition, maintenance, inspection and the like are not needed, so that the life cycle cost of the building is reduced.
本发明公开了一种复合阻尼器，属于结构减震技术领域。主体包括摩擦阻尼单元、黏弹性阻尼单元以及连接单元。通过串联摩擦阻尼器和黏弹性阻尼器，两个阻尼器可以相互补充，可有效地减小风振和地震产生的结构振动。黏弹性体在微震动(如风颤)和中小型地震中率先变形，当振动幅度增大导致黏弹性阻尼单元锁定而强迫摩擦阻尼单元通过摩擦耗能，减少震动。因此，由于两个减振功能由一个阻尼器上组合而成，因此在建筑规划上提供了更大的自由度，并且减震系统的成本也显著降低。此外，由于不需要维护检查等，因此降低了建筑物的生命周期成本。
