Graded energy consumption type metal damper
The invention belongs to the related technical field of energy dissipation and vibration reduction, and particularly discloses a graded energy dissipation type metal damper which comprises a first-stage energy dissipation unit, a second-stage energy dissipation unit and a connecting unit, and the first-stage energy dissipation unit generates plastic deformation through a low-yield-strength metal block to achieve the energy dissipation and vibration reduction effect; the second-stage energy dissipation unit generates plastic deformation through annular metal with the second yield strength to achieve the energy dissipation and vibration reduction effect, and certain rigidity is provided for an externally-connected engineering structure. The connecting unit is used for connecting the first-stage energy consumption unit and the second-stage energy consumption unit to form the whole energy consumption device. According to the graded energy dissipation type metal damper, only the first-stage energy dissipation unit works independently when an external engineering structure generates small displacement, the first-stage energy dissipation unit and the second-stage energy dissipation unit work together when large displacement is generated, and adaptability is high.
本发明属于消能减振相关技术领域，具体公开了一种分级耗能型金属阻尼器，该分级耗能型金属阻尼器包括一级耗能单元、二级耗能单元和连接单元，一级耗能单元通过低屈服强度的金属块产生塑性变形进行消能减振作用；二级耗能单元通过屈服强度次之的环型金属产生塑性变形进行消能减振作用，并为外接的工程结构提供一定的刚度；连接单元用于将一级耗能单元和二级耗能单元连接，组成整体耗能装置。本发明的分级耗能型金属阻尼器在外接的工程结构产生较小位移时仅一级耗能单元单独工作，在产生较大位移时一级耗能单元与二级耗能单元共同工作，适应性强。
