EXPERIMENTAL EVALUATION OF MAGNETORHEOLOGICAL DISK BRAKE

This paper presents experimental evaluation on overall braking capacity of magnetorheological disk brake at various control currents and shaft angular velocity. A magnetorheological brake consists of a rotating disk(s) that is immersed in magnetorheological fluid where the fluid behaviour is changing under influence of magnetic field. The magnetorheological brake was designed in such way that it can be fitted with one or two disks, optionally. The experiments were performed using specially designed test rig to obtain friction, viscous and induced braking torque values in one or two disks configuration. Amplification factor is used to present total braking torque.
