The creating eddy currents through electromagnetic induction changing magnetic flux induces eddy currents in the which create resistance. In normal case if the speed of the conductor and these currents dissipate energy and generate vehicle is very high, the brake does not provide that amount of drag force (Jou et al, 2006) [8]. Therefore, there are no high braking force and it will leads to skidding and wear& tear contacting elements by using this electromagnetic braking of the vehicle. Because of this drawbacks of ordinary brakes, system which will lead to reduce the wear of brake pad. This arises a simple and effective mechanism of braking system situation will also reduce the wear debris pollution into our ‘The eddy current brake’. Eddy current is one of the most environment. outstanding of electromagnetic induction phenomena. Even though it appear many technical problems because dissipative 1.1 Conventional Braking System nature it has some valuable contributions.

The proposed solution is a feasible replacement for the current conventional hydraulic brake (CHB) systems. Unlike CHBs, eddy current brakes (ECBs) use eddy currents and their interaction with an externally applied magnetic field to generate braking torque.

Abstract: The safety of on-orbit satellites is threatened by space debris with large residual angular velocity and the space debris removal is becoming more challenging than before. This paper explores the non-contact despinning and traction problem of high-speed rotating targets and proposes an eddy current brake and traction technology for space targets without any propellant consumption. The principle of the conventional eddy current brake is analyzed in this article and the concept of eddy current brake and traction without propellant is put forward for the first time. Secondly, according to the key technical requirements, a brand-new structure of a satellite generating artificial magnetic field is designed accordingly. Then the control mechanism of eddy current brake and traction without propellant is analyzed qualitatively by simplifying the model and conditions. Then, the magnetic pulse control method is proposed and analyzed quantitatively. Finally, the feasibility of the technology is verified by the numerical simulation method. According to the simulation results, the eddy current brake and traction technology based on magnetic pulses can make the angular speed of target decrease linearly without propellant during the process.

As the vehicle slows, the conventional eddy current brake loses effectiveness. This inherent drawback is due to the use of static/stationary magnetic field in the brake system.

  • Conceptualization of a New Product Development Framework for Eddy Current Braking Systems for Heavy Vehicles in Zimbabwe
    Proceedings of the 2017 International Conference on Industrial Engineering and Operations Management (IEOM) Bristol, UK, July 24-25, 2017 Conceptualization of a New Product Development Framework for Eddy Current Braking Systems for Heavy Vehicles in Zimbabwe Wilson R. Nyemba Department of Mechanical Engineering Science, Faculty of Engineering and the Built Environment, University of Johannesburg, Auckland Park 2006, Johannesburg, South Africa [email protected] Chris Pote, Tauyanashe Chikuku Department of Mechanical Engineering, University of Zimbabwe, P O Box MP 167, Mount Pleasant, Harare, Zimbabwe [email protected], [email protected] Charles Mbohwa Professor of Sustainability Engineering, Department of Quality and Operations Management & Vice Dean for Research and Innovation, Faculty of Engineering and the Built Environment, University of Johannesburg, Auckland Park 2006, Johannesburg, South Africa [email protected] Abstract One of the most critical requirements for safety in vehicles is the availability of reliable braking systems. Most heavy vehicles in Zimbabwe employ the conventional hydraulic braking system. However changes and improvements in technology have seen the introduction of retarders that make use of magnets and eddy currents. The new technology is friction free but still deemed expensive and thus not yet readily acceptable to vehicle manufacturers for fears of reliability and cost. Hydraulic brakes are equally expensive in the long run owing to maintenance and frequent replacement of brake pads and rotors, particularly in Zimbabwe where the road infrastructure has deteriorated significantly over the years. A case study was carried out at a Zimbabwean company which specializes in the sales, service and backup of Scania heavy vehicles, with a special focus on the braking systems.

  • Evaluation of Brake Parameters in Copper Discs of Various Thicknesses and Speeds Using Neodymium – Iron – Boron Magnets
    MATEC Web of Conferences 144, 01003 (2018) https://doi.org/10.1051/matecconf/201814401003 RiMES 2017 Evaluation of brake parameters in copper discs of various thicknesses and speeds using Neodymium – Iron – Boron Magnets G. L. Anantha Krishna1 and K. M. Sathish Kumar1* 1Department of Mechanical Engineering, BMS Institute of Technology & Management, Bengaluru, 560064, India Abstract. Neodymium – Iron – Boron (NdFeB) permanent magnets of 12.5 mm thickness and 50 mm diameter are chosen for analyses because of their higher remanence and coercivity. Experimental analyses were carried out with Copper discs of thickness 4 mm, 6 mm and 8 mm at 2000 rpm, 3000 rpm, 4000 rpm and 5000 rpm. Experiments were conducted with three different positions of magnets such as 2 coaxial magnets, single magnet and single magnet with sudden application conditions. The brake parameters recorded are % speed reduction, deceleration and time taken. In 2 coaxial magnets condition, brake parameters are better in 6 mm thick disc. In single magnet condition, the brake parameters in 6 mm thick disc are found to be more consistent than 4 mm and 8 mm thick discs. In single magnet with sudden application condition, in 4 mm thick disc, the brake parameters are found better. During analysis, very high repulsion was experienced by magnet with 8 mm thick Copper disc at all the above mentioned speeds in single magnet with sudden application condition. For high speed train applications, single magnet condition with 6mm thick disc may be suitable. For high speed automotive applications, single magnet with sudden application condition with 4 mm thick disc may be suitable.

  • Design of Double-Sided Linear Permanent Magnet Eddy Current Braking System
    Progress In Electromagnetics Research M, Vol. 61, 61–73, 2017 Design of Double-Sided Linear Permanent Magnet Eddy Current Braking System Qiang Chen1, *,YingTan2, Guanchun Li1, Jie Li1, and Iven Mareels2 Abstract—This work tries to design an Eddy current braking system that can brake at a very high speed within a short time or a short distance. In order to maximize the braking force and reduce lateral forces that can cause track deformation or damage, a double-sided linear permanent magnet Halbach array is proposed in this paper. Two possible designs (Type I and Type II) have been investigated. By using mathematic models, Finite Element Method (FEM) and experimental results, Type I design of a double-sided linear permanent magnet Halbach array is selected. Compared with the other design, Type I design can provide a much larger braking force. Moreover, the analysis also shows that the mathematic models can well capture the characteristic of Type I design. Thus these models are used to design a set of optimal design parameters such as the length and thickness of permanent magnet block to maximize flux density and braking force per unit mass of permanent magnets. The optimal performance is validated by using FEM. 1. INTRODUCTION In some applications, braking systems need to handle very high speed within a short response time or a short distance. Examples include some high speed testing facilities used to ensure that the designed system can work safely, for example, the AFRL/RHPA Vertical Deceleration Tower (VDT) facility [1], as shown in Figure 1. Hydraulic friction braking systems [2] are usually used to provide enough frictions to decelerate quickly.
