Abstract
Aim. To consider the viscoelastic properties of an electrorheological fluid consisting of silicon dioxide particles in polydimethylsiloxane at different values of electric field strength.
Methodology. The frequency dependences of dynamic modules were approximated using the equations of the structural rheological model. The values of the coefficients of the equations were determined for different values of the field strength.
Results. The possibility of using the equations of the structural model to describe the frequency dependence of the loss modulus and the storage modulus is shown. The relationship between the coefficients of the rheological equations and the magnitude of the applied electric field is established. The relationship between the nature of the rheological curves and the structure of dispersion in the electric field is shown.
Research implications. Equations are proposed that are capable of approximating experimental data in individual sections of the frequency dependence of dynamic modules for an electrorheological fluid. A relationship is established between the calculated coefficients of rheological equations and the structure of the substance
