摘要：

The dynamic stress-strain behavior of an electrorheological (ER) fluid was studied using a Rheometric Mechanical Spectrometer with a specially fabricated high voltage, parallel plate cell. With this apparatus, dynamic properties were determined as a function of the applied field, strain, volume fraction, and oscillation frequency. The experimental technique is rapid and represents a convenient way of obtaining dynamical information of ER fluids. The ER fluid used in the study consists of the hydrated lithium salt of poly(methylacrylate) dispersed in a chlorinated paraffin oil. When an electric field is applied, the suspension behaves elastically at low strains and undergoes plastic deformation at high strain, which is characterized by field-dependent yield stress. This ER fluid behaves like an elastic Bingham fluid.
