摘　　要：简述缸式黏滞阻尼器的结构和力学分析模型;基于幂律流体理论对双出杆黏滞阻尼器的阻尼系数与设计参数的关系进行分析,推导出幂律流体模型的计算阻尼系数表达式;利用MTS对其进行力学性能试验研究,试验结果与计算结果吻合;提出黏滞阻尼器的力学性能试验分析设计与方法。The structure and various mechanical models of cylinder-type viscous dampers are introduced. Based on the power-law fluid model, the relation between the damping coefficient and design parameters of the bi-directional cylinder-type viscous damper is analyzed, and the formula of the calculated damping coefficient is deduced. The performance of the damper was tested by using the Mechanical Testing ＆ Simulation（MTS） system,and the results were almost consistent with theoretical results. The items and methods of the performance test of such damper are presented.
