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 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 ...

The Torque Capacity of a Magnetorheological Fluid Brake Compared to a Frictional Disk Brake
Journal of Mechanical Design, 2018 In this technical brief, the authors compare the torque capacity of a magnetorheological (MR) fluid brake with a conventional frictional disk brake. In the development of the torque models for both brakes, a mathematical expression for the compared torque ratio is presented.

Thermal analysis of magnetorheological brake for automotive application
Applied Thermal Engineering, 2016Abstract Researchers are exploring potential of magnetorheological (MR) brakes for automotive applications. These are superior to conventional hydraulic brakes in terms of response time. However, the technology has not yet matured. This article presents thermal analysis of MR brake (MRB) proposed for an e-bicycle in order to estimate the temperature ...

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

A nonlinear optimal control of a magnetorheological fluid brake
, 2011 The paper describes the design procedure and software/hardware testing of a nonlinear optimal control of a magnetorheological fluid brake. Experimental evaluations allowed to derive and validate a first order nonlinear dynamic model of the device. The obtained model was employed for the development of a braking torque control system.
