With the merits of passive stability, energy-saved and environment-friendly, high-temperature superconductor (HTS) magnetic levitation (Maglev) is regarded as a promising candidate for the future high speed transit. Limited by the experimental conditions, numerical methods are generally employed in most of the current research on dynamic charactristics of high... -

Abstract: Superconducting magnet is capable of generating immensely strong magnetic field due to its large carrying-current capacity and low power loss, making it a promising candidate for transportation systems and power systems, such as EDS train, NMR/MRI and SMES. It is well known that the higher magnetic field can bring above systems better properties. However, the increase in local...

Electrodynamic suspension (EDS) train is one of the most important ways to develop high-speed or ultra-high-speed rail transit. In order to explore the dynamic characteristics of EDS system with figure-eight-shaped coil, this paper transforms the complex electromagnetic field coupling relationship between vehicle coils and ground coils into a simplified circuit relationship, and introduces the...

As a promising candidate for future high-speed transportation, the electrodynamic suspension (EDS) train has drawn considerable attention. The dynamic response of EDS train to eternal excitations could make a great difference on its operating performance, especially in high speed range. Thus this paper focuses on the vehicle dynamics of EDS train, which is separated into two subsystems i.e.,...

The superconducting magnetic levitation(Maglev), realized by high-Tc superconductor subject to high magnetic field generated by permanent magnet of NdFeB, has attracted special interests for applications such as transit and superconducting magnetic bearing(SMB). In the last two decades, several prototypes of HTS Maglev or SMB have been proposed and developed by different groups. Furthermore,...

In this work, the two major electrodynamic suspension (EDS) methods for transportation, namely the permanent magnet - metal plate method and the superconducting magnet - null flux ground coil (figure 8 coil) method, are studied analytically and numerically. Numerical models in different scales were built and the performances of levitation force, resistive force, characteristic speed, et al....

An EDS-Maglev system mainly consists two parts: ground null-flux coils and superconducting magnet on a vehicle or sled. This paper forces on the study of the characteristics of the EDS-Maglev system using dynamic circuit theory. A numerical method including 4-order Runge-Kutta method and inductance space criterion was proposed to improve the calculation accuracy. The calculated results were...

In order to develop levitated transportation systems based on coated conductors tapes, it is important to know not only the information on the levitation force at vertical displacement, but also the data on the stability of the system at lateral displacements of the superconductor with respect to permanent magnets. Data on the lateral stability of stacks of CC-tapes above the magnetic rail...

High-temperature superconducting (HTS) maglev train, with the advantages of low-energy consumption, simple mechanical structure and environment-friendly, is an ideal high-speed transportation in the future. HTS maglev dynamical characteristics considering track random irregularity is important, because the track random irregularity is ineluctable due to the defects produced in installing...

Superconducting Maglev is one of the hottest research directions for superconducting applications. The speed of superconducting Maglev on rail is much faster than conventional rail. And hence the superconducting Maglev is considered as a ultimate substitute for rail traffic. The superconducting magnet made by HTS coils is the core component for superconducting Maglev. This paper illustrates a...

High Temperature Superconducting(HTS) magnet has been proved to be a potential candidate for the maglev system because of its stable self-suspension, low energy consumption and adjustable suspension distance. Nowadays studies on levitation force of HTS magnet are mainly carried out in electromagnetic levitation system, which is between YBCO bulks and permanent magnet guideway. In this paper, a...
