Characteristics of and Carbon-based Electrᄋ- Rheological Rheological

This thesis presents the experimental characteristics of Carbon-based ER fluid. In order to look into the Bingham behavior of these ER fluids, at no load and load into the ER effect in terms of the micro-structure were investigated. In addition, the relationship between the mechanical behavior under various conditions applied to the ER fluid shear mode, physical characteristics were investigated. Were measured by varying the experimental conditions, the electric field from lkV/mm to 3kV/mm, the rotational speed from 0 to 400rpm. Based on the results, each of the ER fluid behavior was completed using the Bingham model. Finally, change of conductivity depending on the temperature difference is investigated and the correlation with dynamic behavior of ER fluid were analyzed considering the characteristics of charge according to DC electric field.
