Abstract

The invention discloses an EDS supporting system for an evacuated tube magnetic levitation train. The EDS supporting system for the evacuated tube magnetic levitation train is characterized in that the train with a circular cross section is arranged in a circular evacuated tube; double-sided linear permanent magnet Halbach arrays and induction plates are arranged on both two sides of the lower half part of the train; and the induction plates are arranged between gaps of the double-sided linear permanent magnet Halbach arrays. The EDS supporting system for the evacuated tube magnetic levitationtrain has the advantages that the EDS supporting system is simple and easy, mechanical friction and air resistance are simultaneously eliminated, superhigh speed operation of the train can be realized and the cost is lower. In addition, compared with a single-sided permanent magnet Halbach array, the double-sided permanent magnet Halbach arrays have the advantages that the levitation stiffness ishigher and the drag-to-lift ratio is greatly increased.

Description

technical field [0001] The invention relates to the field of electric suspension, in particular to an EDS supporting mechanism for a vacuum pipeline magnetic suspension train. Background technique [0002] Maglev trains have the advantages of high speed, safety, small vibration, and low noise. However, due to the dense atmosphere on the surface, it is difficult to further increase their speed. The vacuum tube maglev train eliminates mechanical friction and air resistance at the same time, and is expected to become the next generation of transportation. [0003] At present, the suspension support methods of maglev trains mainly include electromagnetic suction suspension EMS and electric repulsion suspension EDS. Among them, EMS uses the suction force of magnets and magnetic materials as the suspension force, which requires active control to maintain stability, and the system is relatively complicated. EDS uses a permanent magnet or a superconductor as a magnetic source, and...
