Abstract

High-temperature superconducting (HTS) maglev features distinctive merits including friction-free operation, passive self-stabilization and zero inherent forward magnetic drag, rendering it a promising technical solution for future medium-and high-speed maglev transit. Under steady cruising conditions, irregularities on the permanent magnet guideway (PMG) induce vertical vibration and levitation gap fluctuation of the maglev system, which severely impairs vehicle operational stability. To investigate the vertical dynamic performance of the system, a launch test with a target speed of 45 m/s are conducted on the HTS maglev high-speed test platform, and the vibration response characteristics under steady cruising condition are analysed based on the test results. Based on the vibration characteristics, this paper proposes a non-contact vertical vibration suppression method using electromagnetic shunt dampers (EMSDs). The damping performance is verified through equivalent experiments, and further high-speed simulation validation is conducted using the validated dynamic model. This work systematically analyses the vertical dynamic performance of the HTS maglev system and quantitatively evaluates the vibration suppression effect of the proposed scheme, providing a valuable technical reference for the high-speed application of HTS maglev systems.
