Magnetorheological Fluid Preparation Using Various Carriers and Study of Their Properties with Decent Durability

Abstract

Sedimentation instability is a significant problem of magnetorheological fluid.   In most situations, the use of different surfactants to coat iron powder is inadequate in maintaining a stable fluid and often leads to sedimentation within a few days. One of the ideal requirements for magnetorheological (MR) fluid is the preparation of a fluid with outstanding sedimentation stability.   This research explores the use of several carrier fluids and techniques to achieve a more stable magnetorheological (MR) fluid.  Orthogonal experiments are conducted to determine the most effective balance of carrier oil and additive substances. The new findings demonstrate that the most effective combination is achieved by using the produced MR fluid with the compound scheme. This final combination analyses indicate that at normal temperature the best choice has a viscosity of PaS value of 1.924 and a sedimentation rate of 1.51% after four weeks of installation. The optimal MRF exhibits superior sedimentation stability and fluidity over an extended duration.
