코팅처리한 PAQR계 ER유체의 Bingham 특성 및 응답특성고찰

초록

This paper experimentally investigates Bingham characteristics of PAQR Er fluids which are coated with arabic-gum and guar-gum. After composition of four different ER fluids in terms of coating thickness, field-dependent yield shear stresses are distilled at various operating temperatures. In addition, reponse characteristics of ER fluids to step input are evaluated with respect to the intensity of the electric field.
