EXPERIMENTAL STUDY OF SURFACE ROUGHNESS EFFECT ONTHE RHEOLOGICAL BEHAVIOR OF MR FLUID

Abstract

Paper presents the results of shear stress measurements of a commercial magnetorheological fluid using a plate-plate type geometry with a modified working surface. The purpose of the study was to determine the effect of changing the roughness of the measuring plate on the obtained shear stress results. Controlled shear rate tests and Magneto Sweep measurements were carried out for three MR fluid layer heights. The tests were carried out at magnetic field induction in the range of 0 to 680 mT. The study showed that the measurement system's geometric parameters significantly affect the MR fluid's behaviour under test. It was shown that increasing the surface roughness can increase or decrease the measured value of shear stress depending on the test parameters.
