摘　　要：随着国家政策推动,减隔震技术在工程中大量应用。在减震结构实际应用里,黏滞阻尼器因适宜性强、耗能好而被广泛采用。但其力学性能复杂,直接求相关趋势困难。本文借助α=1及α=0时的位移与力关系,得出耗能效果表达式,再用插值公式算出0≤α≤1时的具体式子。随后对Kb/Cd、Kb/(Cdω)等参数展开研究,以阻尼器位移与结构位移比幅值β表示耗能效果。经研究得到不同α下,欲使阻尼器耗能效果达95%以上时,影响参数Kb/(Cdω)的取值范围。据此,在实际工程设计中可合理设计、选择阻尼器支撑构件及参数,实现预期减震效果。With the promotion of national policy,vibration damping technology is widely used in engineering.In the practical application of damping structures,viscous dampers are widely used because of their strong suitability and good energy consumption.However,their mechanical properties are complicated,and it is difficult to find the relevant trend directly.In this paper,with the help of the displacement and force relationship at α=1 and α=0,the expression of energy dissipation effect is derived,and then the interpolation formula is used to calculate the specific formula at 0≤α≤1.Subsequently,the parameters such as Kb/Cd and Kb/(Cdω)are investigated,and the energy dissipation effect is expressed in terms of the amplitude of the ratio β of the displacement of the damper to the displacement of the structure.The range of values of the parameter Kb/(Cdω)is obtained under differentαto make the energy dissipation effect of the damper reach more than 95%.Accordingly,in the actual engineering design,it can be reasonable to design and select the damper support components and parameters to realize the expected damping effect.
