Effect of disc hardness on MR brake performance

Engineering Failure Analysis, 2017
Abstract The online control of frictional force using MR fluid makes Magneto-Rheological (MR) brake an attractive option to replace the conventional disc brake. However, initial experiments on MR brake showed deterioration in the braking performance with time.

MR Fluid Brake for Control of Torsional Vibration

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">The use of a magneto-rheological (MR) fluid brake as a semi-active torsional damper has been investigated. The MR fluid brake can be used as a clutch-type mechanism to transmit torque between a rotating shaft and the brake housing. In that fashion, the MR brake can be used as an adaptive friction damper.

Development of an MR-brake-based haptic device

Smart Materials and Structures, 2006
This paper describes the design, testing and modelling of a magneto-rheological (MR) fluid brake as well as its application in a haptic device. The MR device, in disc shape, is composed of a rotary shaft and plate, an electromagnetic coil, MR fluids, and casings.

Haptic Glove With MR Brakes for Virtual Reality

IEEE/ASME Transactions on Mechatronics, 2009
Haptic gloves open up the world of force feedback by allowing the user to pick up and feel virtual objects in a natural way. In most of the existing gloves, a remote box houses a large number of actuators and sensors. Power to the glove is transmitted via cables.

Gap-Size Effect of Compact MR Fluid Brake

Journal of Intelligent Material Systems and Structures, 2011
MRF are kinds of functional fluids, whose rheological properties, especially shear stresses under shear rates, can be rapidly and repeatedly controlled with application of magnetic fields. CMRFB in which the MRF between multilayered disks works as a torque generator was developed in our previous works.

Pneumatic actuator with embedded MR-brake for haptics

2017 IEEE World Haptics Conference (WHC), 2017
A pneumatic cylinder with an embedded magnetorheological (MR) brake has been developed. The new hybrid actuator benefits from the advantages of MR-brakes and pneumatic cylinders. It can apply forces using compressed air and can resist external forces using the MR-brake.

MR Based Brake-by-Wire System With Self-Energizing and Brake Energy Harvesting Capability

Volume 8: 26th Conference on Mechanical Vibration and Noise, 2014
Brake-by-wire system is a more compact, more efficient brake system using electromechanical actuators instead of conventional hydraulic actuators. Magneto-rheological (MR) fluid is widely used in damping control due to its outstanding controllable properties.

Computer Controlled Rotational MR-brake for Wrist Rehabilitation Device

Journal of Intelligent Material Systems and Structures, 2010
This aricle presents a novel, computer controlled, magneto-rheological (MR) brake actuated, muscular rehabilitation, and evaluation device. The first part discusses various MR brake architectures and compares them. Simple analytical formulae are developed for a set of figures of merit, which point out the role played by the various parameters.

Design of MR brake featuring tapered inner magnetic core

SPIE Proceedings, 2015
In this work, a new type of MR brake featuring tapered inner magnetic core is proposed and its braking performance is numerically evaluated. In order to achieve high braking torque with restricted size and weight of MR brake system, tapered inner magnetic core is designed and expands the area that the magnetic flux is passing by MR fluid-filled gap ...

Design of haptic master featuring small-sized MR brakes

SPIE Proceedings, 2016
In this work, a new type of haptic master featuring small-sized MR brake is proposed and its performances are evaluated. The proposed haptic master consists of base frame, stick grip and small-sized four MR brakes for 3-DOF rotational motion and 1-DOF gripper motion.
