EXPERIMENTAL MODEL DEVICE WITH BULK HTCS RING AND IRON-HOMOPOLAR MAGNETIC GUIDEWAY: MAGLEV TESTS AND NUMERICAL ANALYSES

摘要

In this study the results of magnetic tests, carried out by an experimental model device employing a High Critical Temperature bulk Superconductor (HTCS) ring above circular iron-magnetic guideway, are presented and discussed. The model device simulates, by analogy, the electromagnetic behaviour of magnetic levitation vehicle, using bulk HTCS on board, riding above the iron-magnetic guideway. In the wide range -of work conditions magnetic levitation experiments were conducted and lift and drag forces were measured. Moreover numerical analyses by two-dimensional finite element parametric models were carried out; the results are presented in terms of levitation, guidance forces and flux density distribution.
