Experiments and Analysis of the Limit Stresses of a Magnetorheological Fluid

Abstract

Paper presents the results of a rheological test of a commercial magnetorheological (MR) fluid (MRF-132DG). The researchincludes the problem of measuring and interpreting limit stresses under conditions close to the magnetic saturation of the fluid. Fourdifferent limit stresses were determined, two related to the yield point and two related to the flow point. Methods for determining limitstresses, especially due to excitation conditions, were also analysed. The aim of this study is to determine the effect of selectedparameters on the values of limit stresses of the selected MR fluid. An additional objective is to highlight the problems of definingand interpreting individual limit stresses in MR fluids, particularly in the context of selecting the values of these stresses for the purposeof modeling systems with MR fluids.
