Analysis of Torque in Magnetorheological Rotary Brake
Advanced Materials Research, 2011 A magnetorheological (MR) rotary brake is a device that transmits torque by the shear stress of the MR fluids. In this paper, Bingham model is used to describe the constitutive characteristics of MR fluids subject to an applied magnetic field. The operational principle of the MR rotary brake is introduced.

Design and Experimental Evaluation of a Magnetorheological Brake
International Journal of Advanced Manufacturing Technology, 2003A new magnetorheological (MR) brake prototype was designed, fabricated and tested. Firstly, the rheological properties of MR fluids, in particular the dynamic yield stress, were experimentally investigated based on a Bingham plastic model. The working principles of the MR brake were then analysed and discussed. The equations for transmitted torque were

Design and characterisation of magnetorheological brake system
International Journal of Engineering Systems Modelling and Simulation, 2015 This paper investigates the performance of a magnetorheological brake (MR brake) system in terms of torque generated by various electric currents at various rotational shaft speeds. The MR brake consists of a rotating disc immersed with magnetorheological fluid (MR fluid) in an enclosure of an electromagnetic coil.

Design considerations for an automotive magnetorheological brake
Mechatronics, 2008In this paper, design considerations for building an automotive magnetorheological (MR) brake are discussed. The proposed brake consists of multiple rotating disks immersed in a MR fluid and an enclosed electromagnet. When current is applied to the electromagnet, the MR fluid solidifies as its yield stress varies as a function of the magnetic field ...

Optimization of Magnetorheological Brake
ASME/STLE 2011 Joint Tribology Conference, 2011Quick response and rheological properties as a function of magnetic field are well known features of MR fluids which inspire their usage as brake materials. Controllable torque and minimum weight of brake system are the deciding functions based on which the viability of the MR brake against the conventional hydraulic brake system can be judged. The aim

Design Considerations for Magnetorheological Brakes
IEEE/ASME Transactions on Mechatronics, 2014Design considerations for magnetorheological (MR) brakes are discussed for different geometries. A complete modeling in terms of torque density, efficiency, bandwidth, and controllability is presented. The model assigns a desired magnetic flux density over the fluid surface.

Magnetorheological Fluids Flow Modelling Used in a Magnetorheological Brake Configuration
2019 International Conference on ENERGY and ENVIRONMENT (CIEM), 2019This paper focuses on the behavior of two conventional magnetorheological fluids (MRF 132 DG and MRF 336 AG) together with a non-conventional one (SMR 35% Fe). First, the magnetic flux density of the applied magnetic field was compared with the magnetic flux density of magnetic field in each of our samples.
