Simulation of electrodynamic suspension systems for levitating vehicles. IV. Discrete track systems [PDF]

, 2016
Modelling of electrodynamic suspension (EDS) systems is reviewed for maglev vehicles utilizing discrete tracks. The double-loop null-flux coil suspension concept is analysed using detailed computational models.

Scaling laws for electrodynamic suspension in high‐speedtransportation

IET Electric Power Applications, 2017
Electrodynamic suspension (EDS) relies on the repulsive force created by eddy currents in a stationary conductive body (rail) and a magnetic field generated by an excitation system on a moving vehicle (pod). The excitation system in this paper consists of permanent magnets in a Hallbach array. EDS generates lift forces that levitate the pod reliably at

Reducing the Power Consumption of the Electrodynamic Suspension Levitation System by Changing the Span of the Horizontal Magnet in the Halbach Array

Energies, 2021
In high-speed magnetic railways, it is necessary to create the forces that lift the train. This effect is achieved by using active (EMS) or passive (EDS) magnetic systems.

Levitation‒guidance‒propulsion integrated design for maglev trains based on oblique ring Halbach permanent magnet wheels

机车电传动, 2023
In this paper, a levitation, guidance and propulsion integrated design was proposed for maglev trains on the principle of permanent magnet electrodynamic suspension, in which the Halbach ring permanent magnet wheels and conductor plates were tilted after

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Non-dimensional design approach for electrodynamic bearings [PDF]

, 2012
Electrodynamic bearings (EDBs) are passive magnetic bearings that exploit the interaction between eddy currents developed in a rotating conductor and a static magnetic field to generate forces. Similar to other types of magnetic suspensions, EDBs provide

Magnetic Damping of the Electrodynamic Suspension Type Superconducting Levitation System

IEEJ Transactions on Industry Applications, 1997
The damping characteristic of the bogie motion is one of the most important issues to be investigated in the superconducting magnetically levitated system based on the Electrodynamic Suspension (EDS). We have therefore studied the damping characteristics and the mechanism of magnetic damping.

MODELLING AND ANALYSIS OF PERMANENT MAGNET ELECTRODYNAMIC SUSPENSION SYSTEMS [PDF]

Progress In Electromagnetics Research M, 2014
In this paper, an analytical model of permanent magnet electrodynamic suspension systems (PEDSs) is proposed. Horizontal and vertical magnetic flelds of a permanent magnet (PM) are efiectively approximated by sinusoidal functions. By this means, closed form solutions are obtained for lift and drag forces of PEDSs for the flrst time.

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

Advanced Materials Interfaces, EarlyView.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.
