A new magnetorheological brake`s combined materials design approach

Abstract

© 2017, The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg. Increase of magnetic flux density intensity, in certain parts of a Magnetorheological (MR) brake, was researched in order to improve MR brake`s overall braking properties. This paper proposes a new combined materials approach. New approach achieved magnetic flux density path routing. To verify the effect, two MR brake prototypes: The conventional one and the combined materials one, have been designed, manufactured and tested. Both prototypes had the same geometry. The construction material’s magnetic properties had to be determined by measurements. To increase the overall braking torque, the combined materials MR brake prototype featured non-magnetic housing materials and has successfully yielded significantly larger overall braking torque compared to the conventional MR brake.
