Abstract
The super-high speed high temperature superconductor (HTS) maglev evacuated tube transport (ETT) is a promising transport mode for the future. As a key component of the HTS maglev vehicle, the permanent magnet guideways (PMGs) with different geometrical configurations and iron yoke widths are analyzed by finite element method (FEM). The levitation force of a single onboard HTS maglev device over the designed PMG at different field cooling heights (FCH) is measured by magnetic levitation measurement system. Based on the designed PMG and experimental results, a preliminary scheme of subterranean super-high speed HTS maglev ETT is described in this paper. The HTS maglev ETT is mainly composed of an evacuated tube, HTS maglev vehicle, PMG, propulsion system, station, emergency rescue system, etc. In addition, a subterranean tube that consists of foundation tube and vacuum airproof layer is introduced. In order to convert the stress caused by the air pressure difference between inside and outside of the vehicle, a multi-circular vehicle body is designed. The vehicle is driven by a linear motor propulsion system under the control of a ground controlling system. The scheme of long-distance super-high speed passenger transportation is accomplished by the connection of different vehicles.
