Magnetorheological Fluid Brake – Basic Performances Testing with Magnetic Field Efficiency Improvement Proposal

Abstract

A review of all magnetorheological brake types was presented. Based on overall braking torque analytical comparison for all magnetorheological brake types and other relevant parameters, the most promising design was selected. A test rig, utilizing selected brake type filled with magnetorheological fluid – Basonetic 5030 was manufactured and then tested. To analyze the effect produced by magnetic field on magnetorheological fluid and hence at overall braking torque, the authors used amplification factor. Results were discussed and the magnetic field efficiency improvements were proposed.
