“…Because of these features, electrorheological fluid has attracted significant attention in both scientific and engineering areas during these past years. Several precedent works have been done in the modification of suspension [2][3][4][5], measurement of dynamic responses [6][7][8], inner structure examinations [9][10][11], and theoretical approaches [12][13][14][15]. Application to the machine elements such as clutch, damper [16], and actuator [17,18] is expected.…”

We analyzed a relationship between the viscosity and fine current of the ER suspension aiming for an estimation of the inner structure. This study aimed at an estimation of the inner structure formation via the fine current pass through the suspension. Viscosity and electrical current through electrodes were measured using similar apparatuses, and the relationship between the viscosity and fine current was investigated. The ER suspension was prepared by adding silica particles of 0.5 μm diameter to silicone oil of 0.291 Pa˙s viscosity. The solid volume fraction was 0.20. The voltage was varied from 0 to 1.5 kV/mm. The viscosity of the ER suspension was measured by a falling time in a rectangular tube. As a result, the fine current was found to correlate with the viscosity of the ER suspension. It indicated the possibility that the inner structure of the ER suspension can be estimated using the fine current through the ER suspension. © 2021 Institute of Electrical Engineers of Japan.
