Design and Analysis of Maglev Support System for Vacuum Tube Maglev Transportation

摘要

Vacuum Tube Maglev Transportation significantly reduces the air resistance and eliminates the effects of mechanical friction. With its speed, low energy consumption and other advantages have attracted much attention. The structure and characteristics of its magnetic suspension support are one of the hot research issues. In this paper, an EDS&EMS hybrid support is used. The permanent magnet electrodynamic suspension provides the main levitation and guidance force, and the electromagnetic suspension is used to improve the stability of the support. The physical and simulation models of the support structure are established. Through analysis and simulation, the influence of bearing capacity on air gap and velocity is studied. The results of the two methods are basically consistent. Magnetic field distribution was analyzed in 2D static and transient magnetic fields by ANSYS Maxwell. The causes and trends of errors in analytical methods and simulations are analyzed, which provided a certain foundation for the study of vacuum tube maglev transportation.
