The aim of our research was to determine how sedimentation in magnetorheological fluid influences torque moment of a magnetorheological brake. Five different magnetorheological fluids (MRF-140CG, MRF-122EG, from Lord Corporation, USA, MRHCCS4-A and MRHCCS4-B are from Liquids Research Company, UK and MUDZH-3, made in A. V. Luikov Heat and Mass Transfer Institute, Belarus) were tested. The viscosity of these magnetorheological fluids in the magnetic field of 0–1 T was measured on Anton Paar Physica MCR-301 rheometer. We have selected the fluid with the best parameters to fill up our made magnetorheological brake. To determine sedimentation in magnetorheological fluid was used patent pending method by measuring fluids’ electrical resistivity. Electrical resistivity dependence on sedimentation mathematical model was created. Also four piezo-actuators were used to mix fluid inside the brake. Experimental setup to determine brakes’ torque moment was created.
