Description

technical field [0001] The invention relates to the technical field of permanent magnet electric suspension transportation, in particular to a permanent magnet electric ultra-high-speed transportation device based on a Halbach structure. Background technique [0002] The ultra-high-speed electric suspension system is mainly used in ground flight tests of high-speed maglev trains and ultra-high-speed rocket sleds. There are two types of ultra-high-speed electric levitation systems, permanent magnet electric levitation and superconducting electric levitation. At present, for example, the rocket sled ground flight test in the United States and the high-speed maglev train in Japan all use superconducting electric levitation technology. Both of them use the characteristics of superconducting coils to generate strong magnetic fields to achieve electric levitation, but the supporting equipment required by superconducting coils is complicated. , high cost, and inconvenient to maint...

At present, for example, the rocket sled ground flight test in the United States and the high-speed maglev train in Japan all use superconducting electric levitation technology. Both of them use the characteristics of superconducting coils to generate strong magnetic fields to achieve electric levitation, but the supporting equipment required by superconducting coils is complicated. , high cost, and inconvenient to maintain; while the Halbach structure permanent magnet array is not only simple in structure, but also can generate enough magnetic field strength to realize the suspension and guiding functions. It has many advantages such as low cost, easy installation, easy maintenance, and reusability. A magnet that could replace superconductors
