Design Optimization Method for MR-Brake Actuators

Volume 7: Dynamic Systems and Control; Mechatronics and Intelligent Machines, Parts A and B, 2011
MR-brakes work by varying viscosity of a magnetorheological (MR) fluid inside the brake. This electronically controllable viscosity leads to variable friction torque generated by the actuator. A properly designed MR-brake can have a high torque-to-volume ratio which is quite desirable for an actuator. However, designing an MR-brake is a complex process

Design and analysis of an MR rotary brake for self-regulating braking torques

Review of Scientific Instruments, 2017
This paper presents a novel Magneto-rheological (MR) brake system that can self-regulate the output braking torques. The proposed MR brake can generate a braking torque at a critical rotation speed without an external power source, sensors, or controllers, making it a simple and cost-effective device.

Design of a Novel MR Rotary Brake

2009 WRI World Congress on Computer Science and Information Engineering, 2009
In this paper, a novel MR (magneto Rheology)rotary brake is introduced. A conventional MR brake is equipped with coil, drive and power supply, so,external current should be applied into the coils. But the proposed system has its own generator, so no external current source is not needed.

Research on circular plate MR fluids brake

Journal of Central South University of Technology, 2007
The mechanical properties of certain magnetorheological(MR) fluids were investigated and design method of the circular plate MR fluids brake was presented theoretically. The equation of torque transmitted by the MR fluids in brake was derived to provide the theoretical foundation in the design of brake.

MR-fluid yield surface determination in disc-type MR rotary brakes

Smart Materials and Structures, 2008
Magneto-rheological (MR) fluids are currently attracting a great deal of attention because of their unique rheological behavior. Many devices have been designed using MR fluids, and of potential interest here are disc-type MR rotary brakes. The plug flow region in MR devices is defined as the region where the fluid is not flowing.

Optimization and design of disk-type MR brakes

International Journal of Automotive Technology, 2011
In this paper, first a new design for a disk-type magneto-rheological (MR) brake for automotive applications is proposed and then, a finite element analysis is performed to analyze the resulting magnetic field intensity distribution within the MR brake configuration.
