摘　　要：利用HAAKE RS600流变仪对电流变体进行了强制振荡实验研究,得到了流体在不同剪切应力幅和振荡频率下,电流变体储能模量、损耗模量、损耗因子随剪切应力和剪切频率的变化规律.Electrorheological fluids are new intelligent materials. They are of great significance to study the viscoelastic properties of ER devices in an electric field. In this paper, forced ocsillation experiments of electrorheological fluids have been studied by HAAKE RS600 rheometer and the changes of ERF storage modulus, loss modulus and loss factor with shear stress and shear frequency are obtained for different shear stress rates and oscillation frequencies.
