Torque Characteristics Analysis of a Magnetorheological Brake with Double Brake Disc

Magnetorheological (MR) brake is a sort of electromagnetic that uses the controllable output characteristics MR fluid for braking. In this paper, an with double disc was developed to improve braking performance conventional brakes. The effective damping gaps were increased from traditional two sections four by increasing single disc. By reasonably arranging non-magnetic sleeve inside brake, magnetic flux lines better guided gaps, which utilization rate field, effectively enhanced performance, and also reduced power consumption. structure working principle discussed. field proposed analyzed ANSYS software, theoretical result obtained combining established mechanical model. test rig setup investigate torque brake. experimental results show maximum 18.01 N·m at applied current 2.0 A rotational speed 400 r·min−1, simulation values are basically verified. addition, indicate constant characteristic relatively stable, almost unaffected changes speed. can provide some guidance structural design optimization actuators.
