영문 초록

In this study, Bingham Properties of ER(Electro-Rheological) fluids are experimentally investigated at various temperatures. Especially the viscometer is made in order to measure the effects of temperature. As for the ER fluid to be tested, five types of ER fluids are employed; soluble-gum arabic based ER fluid, an ER fluid of Shokubai, an ER fluid of Loctite, A type fluid and B type ER fluid of Bayer. The first one is composed in-housingly. The Bingham properties of ER fluids is including the dynamic yield stress and the current density. And these prosperities are measured by increasing the electric field from zero to maximum voltage in 25℃, 70℃ and 100℃. Consequently, the yield stress and the current density of the ER fluids are obtained and compared at different temperatures.
