Abstract

The full-scale test platform for ultra-high-speed low-vacuum tube maglev railway includes a 2-kilometer test line and a test base

which is located in Yanggao County

Datong City

Shanxi Province. Research was conducted on the formation mechanism and rapid calculation method of the magnetic resistance of the tube beam (tunnel)

the distribution patterns of the temperature field and deformation control measures of the tube beam

the dynamic performance of the vehicle-magnet-bridge coupled system in the maglev railway

the properties of concrete materials under low-vacuum conditions

and the design methods

structural configuration

and construction technology of the tube beam. The distribution patterns of the magnetic resistance and temperature field of the tube beam were revealed. A vehicle-magnet-bridge coupled vibration analysis model suitable for a 1 000 km/h vacuum tube maglev railway was established

proposing static and dynamic technical parameters for tube beams and establishing an engineering technology system for ultra-high-speed low-vacuum tube maglev bridges. This achieved the cross-integration of superconducting electrodynamic maglev technology

vacuum technology

and traditional bridge civil engineering technology. In July 2024

the demonstration and verification test of the system-integrated superconducting vehicle operating under low-vacuum conditions was successfully completed. The maximum running speed and levitation height of the vehicle met the preset values

and the measured trajectory was consistent with the theoretical curve.
