变间隙粘滞阻尼器的性能分析
|
摘要
基于半主动控制理论,本文提出一种新型的间隙式粘滞阻尼器。通过改变阻尼器缸体内径形成合理的阻尼通道间隙,使阻尼系数具有随位移改变而变化的特性。在幂律流体本构关系的基础上,建立了粘滞阻尼器的阻尼力计算模型。理论计算表明:新型间隙式阻尼器的减振性能显著优于常规间隙式阻尼器。
Based on the semi-active control theory, a new type clearance viscous damper is presented in this paper. Appropriate damping clearances are formed by changing inner diameter of the cylinder, which makes that damping coefficient varies with displacement. According to the constitutive relation of the fluid, academic model for calculating damping force of viscous damper is first developed. The analytical calculation shows that with comparison to normal clearance viscous damper, seismic performance of the new type clearance viscous damper is remarkably improved.
