This paper describes the construction and operation of a superconducting magnetically levitated vehicle applied to urban transportation. The technology was tested with a full-scale prototype named MagLev-Cobra. Comparisons with wheel and rail technology, high speed MagLev and other MagLev technologies are presented and application niches identified. The steps for commercialization will also be addressed.

“…Among these devices, maglev systems consisting of bulk high-temperature SCs and permanent-magnet guideways are particularly important, prototypes in China, Germany and Brazil being good examples. [3][4][5] During the regular operation of a maglev system, however, the levitation body will move away from the working position for some reasons, such as the external disturbance and curved part of the guideway. [6][7][8] In such a case, to reveal the influence of the movement direction of the levitation body on the levitation performance plays an important role in the security design of superconducting maglevs.…”

Influence of movement direction on levitation performance and energy dissipation in a superconducting maglev system

During the regular operation of a maglev system, the superconducting levitation body may move away from the working position due to the external disturbance and the curved part of the guideway. Based on the A − V formulation of magnetoquasistatic Maxwell’s equations, in this paper, a two-dimensional numerical model is applied to study the influence of movement direction on a typical maglev system consisting of an infinitely long high-temperature superconductor and a guideway of two infinitely long parallel permanent magnets with opposite horizontal magnetization. After the highly nonlinear current-voltage characteristic of the superconductor is taken into account, the levitation performance change and the energy dissipation induced by the relative movement of the superconductor and the guideway are discussed. The results show that the levitation force, guidance force and power loss are strongly dependent on the movement direction and speed of the superconductor when it moves away from the working position. If the superconductor moves periodically through the working position, these three physical quantities will change periodically with time. Interestingly, the power loss drastically increases during the first cycle, and after the first cycle it starts to decrease and finally tends to a dynamic steady state. Moreover, an increase in the tilt angle of movement direction will improve the maximum levitation force and, simultaneously, enhance the energy dissipation of the maglev system.

“…It has already been commercialized in TR train and achieved a high speed of 603 km/h in the test of EDS train. Although 29 years has passed since YBCO high-temperature superconductor was discovered, research and development of HTS maglev vehicle is still under laboratory study, mainly in China, Germany, Brazil and Japan [11][12][13][14]. In 2016, the team from Federal University of Rio de Janeiro of Brazil designed a full-size manned HTS maglev vehicle and a 200 m-long straight track to carry out the test with a speed of only 7 km/h.…”

Static and dynamic stability of the guidance force in a side-suspended HTS maglev system Dajin Zhou, Chenyu Cui, Lifeng Zhao et al.High-efficiency and low-cost permanent magnet guideway consideration for highTcsuperconducting Maglev vehicle practical application Z Deng, J Wang, J Zheng et al. IntroductionTaking advantage of flux pinning characteristic of YBCO bulk, HTS maglev system has excellent selfstability [1]. It is widely used in magnetic bearing [2,3], maglev vehicle [4-6], maglev launch [7,8] and other fields. Compared with conventional wheel rail train, maglev vehicle operates more stably without noise, and has smaller turning radius. It is an important solution for high-speed ground transportation in the future.
