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.

Energy-saving control of an unstable valve with a MR brake

Proceedings of the 2005, American Control Conference, 2005., 2005
In fluid power systems, excessive heat often causes solenoid failure. Heat, as well as useful power of a solenoid, is associated with the current. In this paper, we attempt to alleviate the requirement for the solenoid power, thus reducing the heat generation accordingly.

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.

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.

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.

Spherical MR-Brake with Nintendo Wii Sensors for Haptics

2010
This research improves the position measurement system of a magnetorheological (MR) spherical brake we recently designed. The brake is a multi-DOF actuator. The initial design had a position measurement system with infrared (IR) sensors. Although the IR sensors gave good results, there were some performance degradations in the brake due to the noise in

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.

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.

Development of virtual reality bike with cylindrical MR fluid brake

2012 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2012
Cycling is a healthy and moderate aerobic exercise for the elderly and it works well not only to their physical functions but also to their mentalities. In order for the exercise machine that can facilitate the moderate aerobic exercise for users who cannot do real cycling, we have developed the virtual reality bike (VR Bike) with a cylindrical MR ...
