摘　　要：提出一种无轴黏滞阻尼器,其基本原理是通过油腔本身的变形驱使黏滞流体往返通过阻尼孔而耗散能量。通过性能试验和有限元分析,初步验证了该阻尼器的构造方案是可行的。基于结构振动控制Benchmark模型对该类型阻尼的减振性能进行研究,结果表明该类阻尼器具有很好的减振效果。A shaftless-leakage protection viscous damper was presented, its basic principle was that the deformation of oil cavity itself drove viscous flow through damping hole back and forth so that energy dissipated.Through performance test and finite element analysis, the feasibility of the damper structure schemes was preliminary verified. The results of the type of damping vibration reduction performance based on Benchmark model of structural vibration control showed that the shaftless-leakage protection viscous damper has a good damping effect.
