Synthesis and Characterization of Innovative Type Magneto-Rheological Fluid

Abstract

This research work is concerned with synthesis of an innovative type of magneto-rheological fluid (MRFluid) using edible low-cost soya bean oil as a carrier liquid with three different concentrations of electrolytic iron powder as a suspended medium and additives as a commercial grease. The field-dependent rheological properties of MRFluid samples were tested under different magnetic field conditions using rheometer. The results of the field-dependent-rheological properties of the prepared MRFluid samples show good agreement with commercial MRFluid. This directly indicates that the proposed innovative type of MRFluid can be used in automotive suspension systems, dampers, vibration control devices and so forth. Sedimentation test is also carried out in order to know the stability of the MRFluids.
