DAMPING PROPERTIES OF ER FLUID ON PATTERN ELECTRODES : CONSIDERATION ON COMPOSITION OF ELECTRODES AND ELECTRIC FIELD

Abstract

Various devices and equipment using ER effects have been developed and studied. When an ER fluid is used in shear mode, the ER fluid is filled between a pair of opposing parallel electrodes. We have proposed one-sided pattern electrodes that have many advantages. In this paper, four kinds of composition of electrodes including the both-sided electrodes and one-sided electrodes are considered. The electric fields are analyzed. The manifestation of ER effects is experimentally verified in four kinds of composition.
