Abstract: 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.

Key words: Electrorheological fluids, oscillatory shear, viscoelastic
