Abstract

Objectives: The aim of this work is that how the MR fluids can be prepared. Methods/Statistical Analysis: This paper highlights on the recent development of MR fluids. In this paper the preparation of MR fluid are described. Base fluid is taken as silicone oil and micron sized iron powder is mixed in it. To reduce the sedimentation White lithium grease is also mixed as an additive in the prepared fluid. Finding: The sedimentation analysis is important aspect in case of MR fluids. The composition of MR fluid samples is taken from the base paper. For the preparation of MR fluids three components are used. These three components are base fluid, metal particles, additives. With different composition of three components three MR fluid samples are prepared. The sedimentation properties are studied by visual inspection. The effects of temperature on the viscosity of the prepared fluid samples are investigated. The viscosity of the MR fluid plays an important role in its working. The viscosity of the MR fluid depends on its composition, more the iron content the viscosity will be higher. At different value of temperatures the value of viscosity is calculated. The effects of temperature on viscosity are observed. Application/Improvements: An electrical stirrer is used for the preparation of the MR Fluids. Magneto rheological fluids are the smart materials whose properties change rapidly and can be controlled easily in the presence of an applied magnetic field.
