摘　　要：以涡－流函数法研究了硅油流体在扭振阻尼器内部的流动规律，在一定简化条件下，用有限元法对受叶片初始扰动下的流体流动性态进行了数值模拟，得到了流场规律．通过涡场强度的分析，揭示了有关阻尼机理，并利用频响函数法对典型阻尼减振系统进行了实验．结果表明，文中采用的方法在指导设计中是可行的．The paper discusses the flow characters of silicone oil torsion damper using eddyflow function method. Via finite element method, simulate the unsteady flow problem of the viscous liquid excited by the motive blade under some simplifications. Damping has a direct relation with the eddy intensity. In the end, damper is tested in a vibration system via frequency response function. The results show that the simplified method is feasible for directing the design.
