The Rheological Behavior and Thixotropy of Electrorheological Suspensions in Differing Temperature/Velocity Conditions (Rheologicheskoe Povedenie i Tikostropiya Elektroreologicheskikh Suspenzii v Razlichnykh Temperaturno-Skorostnykh Rezhimakh)
Abstract
The practical application of the electrorheological effect (ERE) depends to a decisive extent on the mechanical, thermo-physical and structural properties of the electrorheological suspensions (ERS). It is convenient to categorise ERSs by their particle concentration ranges: very dilute ones - up to 1% by volume (for dielectric motors), medium concentrations (working medium for hydrosystems, dampers, vibrators) and high concentrations (for strengthening of components, for systems with controlled slipping). ERS are made up of a non conducting dispersion medium, particles of a disperse phase and sometimes a surface-active substance (SAS). The activity of the suspensions in the electrical field is chiefly dependent upon the specific polarizability and conductivity of the particles. At the present time the most comprehensive study has been made of suspensions of moistened silica in a non conducting medium (eg in hexadecane or in transformer oil).
