The use of an electro-rheological fluid (ERF) in some applications may require a high damping capacity. This paper presents the design and evaluation of a prototype damper using an electro-rheological grease (ERG) with high zero electric field viscosity. In designing the ERG damper several issues such as: a) maintaining a constant internal damper volume, b) minimizing the fluid shear in flow paths (other than in the electrode gap region) which reduces adverse effects on damper performance and, c) allowing the adjustment of the electrode gaps, are considered. Comparisons are made between the performance of the ERG and an existing ERF. The ERG demonstrates higher damping capacities at low frequencies than those of the ERF.
