no-load condition and in the manned condition. Measurements need several people
simultaneously performing the operation (Fig. 6.69).
Under no-load condition, the on-board Maglev equipments were fully cooled at
the FCH of 42 mm. Henceforth, vehicle support was removed, and the net levitation
height (work height) was 26 mm for the free levitation vehicle. The net levitation height
was the gap between the PMG surface and the bottom surface in on-board Maglev
equipments.
The experimental results of the guidance forces are listed in Tab. 6.15 and Fig. 6.70.
It can be seen that the lateral guidance forces of the entire HTS Maglev vehicle were
large enough (Fig. 6.71). The guidance forces at a 20-mm displacement were 4407,
2908, and 1980 N for FCH of 12, 26, and 42 mm, respectively. The guidance forces
at 11 mm displacement were 3003, 1913, and 1420 N for FCHs of 12, 26, and 42 mm,
respectively. The experimental results for the guidance forces under the maximum
lateral displacement of 20 mm are shown in Fig. 6.70. The lower the FCH, the higher
the guiding force. This is because the trapped flux was more at the lower position.
