Abstract

The purpose of this research was to investigate and overcome the limitations of Electrorheological (ER) fluids and to introduce this advanced technology at WMU. Electrorheological (ER) Fluids are a special class of fluids, which exhibit a reversible, infinitely variable phase transition from a liquid to a solid/semi-plastic state, in the presence of an electric field.

ER fluids can provide a unique solution to the problems of vibration isolation of systems. The applications are currently limited due to the high voltage requirements, electric power related heating and limited research into wear/abrasive characteristics of ER fluids.

A specially designed and constructed "electro-viscosimeter" and power source, were employed to determine the optimal electric signal, reduce the power input and the resulting fluid temperatures of ER fluid components. The research should prove invaluable in the advancement of the current applications of ER fluids. It should also lead to introduction of innovative applications of ER fluids.
