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.

Functions:

●  Dynamic stability measurement of HTS maglev equipment (liquid nitrogen vessel included HTSCs) at different velocity;

●  Measurement of levitation force and guidance force of both single and multi HTSCs specimens;

●  Measurement of levitation force stiffness and guidance force stiffness of both single and multi HTSCs specimens;

●  Measurement of levitation force and guidance force change at different levitation gap.
