Abstract
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 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 magneto-rheological 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.
