On-state Torque Optimization for Synthesized MR Fluid

摘要

Magneto-Rheological (MR) fluids are the suspension of magnetizable particles in a carrier fluids and their rheological properties viscosity etc. can be changed by varying the magnetic field applied to it. Due to such variable characteristics, these MR fluids find wide application in various automotive industries devices e.g. MR brakes and MR clutches etc. In MR brakes, the MR fluids generate a resisting torque (between housing and rotor) within milliseconds on the application of magnetic field. In the present work, the optimal values of MR fluid constituents is obtain which give the high values of on-state torque. For this, 18 samples of MR fluids are prepared and their compositions are selected using L-18 orthogonal array
