영문 초록

In this study, the shear mode measuring devices which is used in general applications of ER fluid is proposed and Bingham Properties of ER(Electro-Rheological) fluid depended on various electrode shapes and materials is measured. Shear forces depended on radius variations is measured similarly. When the torque of ER fluid which is measured is same, the shear stress shows the size which is identical. The case where the torque which is measured will be same, the shear stress is of one size whether the gap of electrodes is changed. As a result of experiment, shear stress is increased with increasing shear rate. Also Bingham Property is increased with increasing electrical field strength. The experimental results by the proposed equipment is almost same with the conventional equipment by increasing electrode radius. ER effects is increased with the decreasing of the electrode gap.
