And Performance

Bulk high temperature superconductors are usually used as arrays due to the limited size and performance of a single bulk. To find a reasonable array pattern for the superconducting maglev vehicle, we studied the levitation force of four multi-seeded rectangular YBaCuO blocks with three possible arrays above a permanent magnet guideway (PMG). Experimental results show that the levitation force can be improved through an optimal array pattern of the bulk superconductor. The method is to avoid the joint gaps of bulk arrays in a strong magnetic field area of the PMG thus improving the utilization rate of the applied magnetic field. The optimal array pattern will be helpful to improve the levitation performance and reduce the quantity of onboard superconductors.

The Relationship

In order to make the levitation performance of the high temperature superconducting (HTS) magnetic levitation (Maglev) vehicle more stable and safer, in this paper, using a cryogenic measurement system, we measured the levitation forces of YBCO bulk above halbach-type permanent magnet guideway (Halbach PMG) in the temperature range from 77 K to 60 K, then in the condition of deep cryogenic, the levitation forces of YBCO bulk at different field cooling heights (FCHs) were also measured, according to which the levitation stiffness were calculated. The results show that the levitation stiffness of HTS/PMG Maglev system is better at lower temperature. Moreover, when the temperature of YBCO bulk decreases from 77 K to 73 K, the levitation stiffness largely increases in any FCHs. However, after the temperature of the bulk decreases to 73 K, the rate of the levitation stiffness increased gradually reduces. The results are helpful to HTS Maglev vehicle application.
