Abstract

Disclosed are the dynamics and mechanical stability of the UAQ4 experimental small-scaled superconducting magnetically levitated vehicle which floats in a stable condition above the magnetic track in all phases of motion, zero speed included The magnetic suspension system is based on the interaction between high-temperature superconductors (HTS) onboard the vehicle and the permanent magnets distributed on the track. The dynamic behavior of the suspended vehicle at standstill is analyzed by a two-degree-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 UAQ4 magnetically levitated vehicle.
