Abstract
The dynamic measurement of high temperature superconducting (HTS) magnetic levitation (Maglev) vehicle is a very important and difficult problem. In order to investigate the dynamic characteristics behavior of HTS Maglev, an HTS Maglev dynamic measurement system (SCML-03) was successfully developed in Applied Superconductivity Laboratory (ASCLab) of Southwest Jiaotong University, P. R. China. The system is mainly constituted by the circular permanent magnet guideway (PMG), liquid nitrogen vessel, data acquisition and processing, mechanical drive, autocontrol and so on. The PMG is fixed along the circumferential direction of a big circular disk with diameter 1500 mm. The maximum linear velocity of the PMG is about 300 km/h when the circular disk rotates round the central axis at 1280 rpm. The liquid nitrogen vessel with high temperature superconductors is placed above the PMG, and the vessel is not three-dimensional rigid connection with measurement sensor devices. These sensors can detect weak force change from three-dimensional directions. The maximal vertical and horizontal support force of the system are 3350 N and 500 N, respectively. Test process and results of the HTS Maglev dynamic test system are reported.
