Paper Abstract

A fluid model for the evaluation of electrorheological grease (ERG) is presented. This model considers the influence of a Non-Newtonian fluid using a Herschel-Bulkley fluid model. Fluid compressibility was included using a lumped parameter dynamic system model. The optimal model parameters were determined by matching theoretical and experimental data for an existing ERG damper. Results indicate that a good match between experimental and theoretical data was achieved using the Herschel-Bulkley fluid model. A sensitivity analysis indicated that the model was insensitive to the mass of the fluid, but sensitive to the bulk modulus of the fluid.
