位移放大型阻尼器研究进展

Research progress of displacement amplification dampers

传统的位移相关型阻尼器在结构变形较小时往往难以充分发挥工作性能。为此,可采用特殊的构造形式和安装方法,将结构的变形或位移放大数倍后再输入阻尼器,进而提高阻尼器的工作效率和耗能能力。阐述了位移放大的基本概念,并对4种典型的位移放大型阻尼器进行了分类介绍,可供理论研究和工程应用参考。

The traditional displacement dependent dampers cannot give full play to its performance when the structure deformation is small.To this end,specific construction forms and installation methods can be used to magnify the deformation or displacement of the structure several times and then input the damper,so as to improve efficiency and energy dissipation capacity of the damper.The mechanism of displacement amplification was presented,four typical categories of displacement amplification dampers were introduced,providing a reference for future research and application.
