摘要
本文首先研究了双出杆油缸间隙式粘滞阻尼器的构造，讨论了不同类型粘滞流体的特性;;然后，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;;最后，设计制作了两个粘滞阻尼器，进行了详细的性能试验，通过试验结果的统计分析，得到了阻尼力计算模型的幂指数。
In this paper, firstly, the struCture of clearance viscous damper is studied and thecharacteristics of different kinds of viscous fluid are discussed. Secondly, based on the constituteof fluid, the calculation model of viscous damper damping force is established. Finally, twoviscous dampers are designed and manufactured and performance is tested.By statistic analysis of experiment results, power exponent of the calculation model of the damper output forceis got.
