A Halbach permanent magnetic guideway (PMG) is presented for improving the levitation performance of high-temperature superconducting (HTS) magnetic levitation (maglev) vehicle. The studies have shown that an optimality criterion is used for evaluating the levitation performance for the HTS maglev vehicle.

The dynamic characteristics behavior of high temperature superconducting (HTS) magnetic levitation (Maglev) is examined by developing an HTS Maglev dynamic measurement system (SCML-30). The Maglev parameters are obtained at different rotation speed by the feasible measurement system, SCML-30.

The article discusses the design and operation of the laboratory-scale high temperature superconducting (HTS) Maglev launch system developed in the Applied Superconducting Laboratory (ASCLab) of Southwest Jiaotong University in China.

The successful development of an update high temperature superconducting Maglev measurement system (SCML-02) is discussed. Findings reveal that SCML-02 is capable of high measurement precision, instant measurement at movement of the measured high temperature superconducting (HTS) specimen, and guidance and measurement of three dimensions at one time.

The first man-loading high-temperature superconducting (HTS) Maglev test vehicle in the world was successfully developed on Dec. 31, 2000 in Applied Superconductivity Laboratory, Southwest Jiaotong University, China. Heretofore over 24 500 passengers took the vehicle, and it has been operating back and forth about 400 km. The HTS Maglev vehicle provides inherent stability both in the vertical and lateral direction, so no control system is needed. The only control system is used for linear motor driving devices. The melt-textured YBaCuO bulk superconductors are fixed on the bottom of a liquid nitrogen vessel and cooled by liquid nitrogen. The bottom thickness of the rectangle liquid nitrogen vessel with thin wall is only 3 mm. The onboard HTS Maglev module is over the guideway. The guideway consists of two parallel permanent magnetic tracks, whose concentrating magnetic field at 20 mm height above the surface is about 0.5 T. The levitation forces of 8 HTS maglev modules were measured. The total levitation force of 8 onboard Maglev modules was 10431 N at the levitation gap of 10 mm, and 8486 N at the levitation gap of 15 mm, respectively. These results were measured on May 28, 2002. [ABSTRACT FROM AUTHOR]

When the velocity of the normal ground traffic transportation is higher than 350 km/h of the speed limit, not only the running noise of the ground traffic vehicle is higher, but also the 90% driving power is dissipated in the aerodynamic resistance. The high speed may be realized when a high temperature superconducting (HTS) Maglev vehicle runs in low-pressure tube or evacuated tube transport (ETT). Its speed is over 3000 km/h. As a new ground transportation system the HTS Maglev vehicle is presented after the experiment results of HTS Maglev vehicle are discussed in this paper. [ABSTRACT FROM AUTHOR]
