Disclosed is the dynamics and mechanical stability of the UAQ4 experimental small scaled superconducting magnetically levitated vehicle that floats in a stable condition above the track in all phases of motion, zero speed included. The magnetic suspension system is based on the interaction between high temperature superconductors (HTS) set into proper “skates” of the vehicle and permanent magnets distributed on the track. The dynamic behavior of the suspended vehicle is analyzed by two degrees of freedom model refined by experimental data. The dumping analyses and tests have been accomplished and the results are presented and discussed in terms of time histories (vertical and rotational oscillations) performed by varying the external actions of the system. These results are required for the practical mechanical design of the full-scale HTS magnetically levitated vehicle.

Abstract
Disclosed is the dynamics and mechanical stability of the UAQ4 experimental small scaled superconducting magnetically levitated vehicle that floats in a stable condition above the track in all phases of motion, zero speed included. The magnetic suspension system is based on the interaction between high temperature superconductors (HTS) set into proper “skates” of the vehicle and permanent magnets distributed on the track. The dynamic behavior of the suspended vehicle is analyzed by two degrees of freedom model refined by experimental data. The dumping analyses and tests have been accomplished and the results are presented and discussed in terms of time histories (vertical and rotational oscillations) performed by varying the external actions of the system. These results are required for the practical mechanical design of the full-scale HTS magnetically levitated vehicle.Pubblicazioni consigliate
