This article concerned with technological innovations and performance of the UAQ4 Italian maglev train project which aims mainly to reduce energy consumption by eliminating any ordinary resistance to motion (magnetic drag included), except the aerodynamic drag if it operates in atmospheric environment. The technological feasibility of the UAQ4 suspension and propulsion devices has been patented and successfully laboratory tested. The train architecture and the work’s principles of suspension and propulsion devices are all innovative, with concepts and technologies close to the aeronautical transport system.

Suspension Dynamic Behaviour of HTS Magnetically Levitated Bogie

This article illustrates the dynamic behaviour of the suspension of the bogie of the UAQ4 experimental superconducting levitating train. The levitation system uses high temperature (liquid nitrogen cooled) superconductor bulk materials on board and permanent magnets distributed on the guideway. The magnetic interaction between the two, and the Meissner effect, both lift and guide the vehicle. A model with one degree of freedom of the bogie is developed and parametric dynamic analyses are performed and discussed by varying the most significant system parameters.

“…The Italian HTS Maglev experimental system UAQ4 has been developed at the University of L'Aquila; it is based on vertical suspension mode. The dynamic behavior of the prototype was first studied by performing linear analyses and tests in a standstill condition [15,16]. Moreover, a study addressing the effect of a transition curve on the dynamic behavior of the bogie has been recently performed.…”

It is now recognized that high-temperature superconducting (HTS) technology has a significant potential for future magnetic levitation (Maglev) transit system applications due to the advantages of self-stable levitation, being free of electric power and magnetic drag to the vehicle motion, and system simplicity. This article provides a characterization method of the experimental transport system Maglev levitation module developed at the University of L’Aquila (Italy). More specifically, the lifting and guiding behavior of a single V-shaped Maglev module, which is unique for this type of application, is analyzed and tested. Its working principle is based on the interaction between HTS “skate” onboard of the vehicle and the magnetic field generated by the permanent magnets distributed on the guideway (PMG). A single scaled levitation module was built and tested under quasi-static conditions using dedicated measuring equipment by varying system parameters such as vertical gap, lateral offset, and field cooling height. The latter determines the amount of interacting magnetic field that is trapped in the HTS core during its transition from the resistive to the superconducting state and which, in turn, interacts with the field generated by the PMG to create the suspension phenomenon. The Maglev module’s dual behavior due to the double phenomenon of repulsion and attraction has been verified and tested in terms of vertical and lateral forces by varying system parameters. The dual “push and pull” force allows the phenomenon of vehicle driving to be enhanced.
