Abstract

Two magnetorheological fluids were designed, elaborated and tested with the objective of being used like brake in different applications. The fluids were obtained from ferromagnetic iron oxide particles of diluted commercial use in a oil emulsion. The volumetric fraction and the quality of the emulsion were experienced until obtaining a sample with a time of sedimentation sufficiently great to work with it. The magnetorheological fluids (MR) were characterized by means of viscometer. The samples were immersed in a magnetic field generated by magnets and coils of commercial use. The density of magnetic flux was determined and dynamic viscosity was observed for the imposed deformation. The found values were compared with studied publications.
It is concluded that is feasible to reproduce experiences and results obtained by other investigators. MR fluids used and the generated magnetic fields are reasonable with low resources. The studied viscosity of MR fluids was increased, in presence of the magnetic field, so the foretold. The value of resulting viscosity adjusts qualitatively to the curves presented/displayed by other authors. From these results, the design of fluid mechanical
devices that use MR fluids with the studied characteristics for different applications is planned..
