A Study on Brake Torque for Traction Motors by Using the Electric Brake

2014
In this paper, a scaled model propulsion system was designed and tested for a electrical brake until stopping of the vehicles. A brake torque control method at the moment of vehicle stop was proposed accordingly. The test results for the electric brake were drawn while controlling the motor at low speed until the stop of the electric locomotives. Also,

Design of an Innovative High-Torque Brake

Advanced Materials Research, 2011
The paper shows the design of an innovative magneto-rheological fluid brake (MRF brake). The integral brake torque from a conventional MRF brake is not quite large since it commonly adopts a single ring-type electromagnetic pole to produce magnetic flux to change the MRF viscosity.

Magnetic flux distribution and braking torque of a grooved eddy current brake

2020 2nd International Conference on Computer and Information Sciences (ICCIS), 2020
Motorcycles generally require an optimal braking system, eddy current brake (ECB) can be used as an alternative to conventional braking systems. Design unipolar axial ECB with an electromagnet used in this research. ECB performance can be influenced by some factor, one of them is changing the form of the surface of a conductor.

Technique for reducing brake drag torque in the non-braking mode

JSAE Review, 2000
Abstract Brake drag torque under non-braking conditions with the disc rotating freely causes fuel economy to decline and induces disc thickness variation, which gives rise to brake judder. In this study, the effect of the contact condition between the pads and the disc rotor on disc rotor wear was first studied.

An original braking controller with torque sensor

Proceedings of IEEE International Conference on Control and Applications CCA-94, 1994
The present evolution of regulated braking systems requires the knowledge and control of dynamic parameters of the vehicle during the braking process. In a classical ABS system, the chassis speed is only known approximately and this is not sufficient to control the slip ratio.

Braking torque control of the multi-disc magnetorheological brake based on the brake pedal

Engineering Research Express
Abstract 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

Analysis of Torque in Magnetorheological Rotary Brake

Advanced Materials Research, 2011
A magnetorheological (MR) rotary brake is a device that transmits torque by the shear stress of the MR fluids. In this paper, Bingham model is used to describe the constitutive characteristics of MR fluids subject to an applied magnetic field. The operational principle of the MR rotary brake is introduced.

Brief Introduction of Brake Line Pressure and Brake Torque Transmission Model

Applied Mechanics and Materials, 2011
If static model of brake pipe pressure and torque model were used in brake system analysis and neglect their dynamic performance, it could cause bigger difference between simulation results and real condition. Some main dynamic models from experiments research are presented with brief introductions.

A control system for maintaining constant braking torque on a disk brake dynamometer

15th Annual Conference of IEEE Industrial Electronics Society, 2003
Most manufacturers of composite friction materials do not possess adequate facilities to test their products dynamically. A practical solution is to simulate the braking process in the laboratory mechanically by means of a disc brake dynamometer. The authors describe a control-system design for the dynamometer.

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.
