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.

Magnetorheological Brake for Haptic Rendering
2008This paper addresses the design and characterization of a single-disk magnetorheological fluid brake developed for haptic rendering. An analytical method was used for dimensioning. Brake is tested under constant current and velocity inputs. We observe that torque has a low dependence on velocity and that it has a hysteretic evolution with current as a ...

The Development of a Hybrid Antilock Braking System Using Magnetorheological Brake
Applied Mechanics and Materials, 2013This paper proposes a novel hybrid antilock braking system (ABS) with the combination of auxiliary brake and a magnetorheological (MR) brake with multiple poles. The operation concept of this MR brake is different to conventional MR brake. Its output torque proves the ability to be used in motorcycle brake system.

Design and experiment of a new magnetorheological brake
International Journal of Applied Electromagnetics and Mechanics, 2015Conventional MR brake design with single ring-type electromagnetic pole is insufficient in torque increment. A new magnetorheological (MR) brake is designed in this paper to employ magnetic flux effectively on the overall surface of a rotating brake disc.

Magnetorheological suspension electromagnetic brake
Journal of Magnetism and Magnetic Materials, 2004Abstract The magnetorheological suspension (MRS) brake is of the monoblock type. The main part of the electromagnetic brake is an electromagnet, between whose poles two MRS disks are placed. For distances between disks of 0.65×10−3 m±10%, revolutions of the electric motor, coupled to the electromagnetic brake, ranging between 200 and 1600 rev/min and

Simulation and investigation of magnetorheological fluid brake
2008 13th International Power Electronics and Motion Control Conference, 2008The paper deals with coupled electromagnetic, hydrodynamic and mechanical motion phenomena in magnetorheological fluid (or simply MRF) brakes. The governing equations of these phenomena are presented. The numerical implementation of the mathematical model is based on the finite element method.

Development of a magnetorheological brake with a slotted disc
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2015A conventional disc wears out and the brake pollutes the environment. Brake pad dust is reported to be the largest source of environment pollution 1 . The particles emanating because of wear of the brake pad pollute the environment 2,3,4 .

Selection of Materials in Designing Magnetorheological Brake
Applied Mechanics and Materials, 2014The braking system is among the most significant active safety systems in a vehicle application for preventing injuries and property damage. Whether for light or heavy vehicles, brakes are no longer a small issue whereas it becomes a crucial problem to maintain the safety and to avoid the unpredictable cases especially on the road.

Design and Analysis of a Small-Scale Magnetorheological Brake
IEEE/ASME Transactions on Mechatronics, 2022This article presents the design and performance of a small-scale magnetorheological (MR) brake, with the fastest time constant and highest torque-to-mass ratio among small-scale MR brakes (i.e., those with a diameter less than 40 mm and a thickness less than 30 mm), which are typically designed for use in small haptic or robotic devices.

Braking torque control of the multi-disc magnetorheological brake based on the brake pedal
Engineering Research ExpressAbstract Magnetorheological (MR) transmission technology is an innovation application of the MR effect in the field of engineering transmission. The MR brake with MR fluid as the working medium is a kind of non-contact brake, which has wide application prospects in soft braking systems. The proposed MR braking system uses the MR brake as
