阻尼器作为一种廉价高效的被动减震装置目前已广泛应用于我国建筑领域,而菱形阻尼器以其特殊的构造,能够在较小阻尼系数下提供给结构较大阻尼比,同时可以在结构水平位移较小时提供阻尼力。研究非线性菱形黏滞阻尼器的力学特性,推导了菱形黏滞阻尼器的等效阻尼比公式,对比阻尼器为结构提供相同附加阻尼比的情况下,黏滞阻尼器和菱形黏滞阻尼器之间的减震效果。结果表明,由于放大系数的原因,菱形阻尼器可以以小阻尼系数来提供大阻尼比。
As a kind of cheap and efficient passive damping device, damper has been widely used in China’s architectural field. Diamond damper, with its special structure, can provide a large damping ratio to the structure with a small damping coefficient, and can also be used in the structure. The damping force is provided when the horizontal displacement is small. The mechanical properties of the nonlinear diamond viscous dampers are studied, and the equivalent damping ratio formula of the rhombic viscous dampers is deduced. The viscous dampers and rhombic viscous dampers are compared when the dampers provide the same additional damping ratio for the structure. Vibration damping effect between. The results show that due to the amplification factor, diamond dampers can provide a large damping ratio with a small damping factor.
