Abstract

In recent years, there have been numerous researches on magnetorheological fluid (MRF) and its applications. A number of MRF-based devices have been developed such as clutch, brakes, valves, dampers, engine mounts, etc. Among the MRF-based devices, magnetorheological brake (MRB) is one of the most interested by researchers. There have been many researches on development, improvement of MRB and its application in industry. MRBs are also commercialized these days. In order to improve MRB performance, many types of MRB have been proposed and evaluated such as: disc-type MRB, drum-type MRBs, hybrid-type MRB (a combination of disc-type and drum type MRB), T-shaped rotor MRBs, tooth-shaped rotor, drum-type with serpentine magnetic flux path, MRBs with multiple magnetic poles and multiple MRF layers. In order to get the best performance characteristics of the MRBs, several researches focused on optimization of the MB structures considering braking torque, mass/ size, power consumption, off-state torque, working temperature. This research focuses on the state-of-the art in researches of MRBs and proposes some solutions to improve performance characteristics of MRBs.
