Abstract
The high-temperature superconductor (HTS) magnetic levitation vehicle (Maglev) is one of the important modes in the rail traffic. In order to study the levitation characteristics of HTS Maglev, the captured magnetic field characteristics of HTS bulk are analyzed in the different field cooling heights. Based on the thought of frozen image model, the equivalent processing method for HTS bulk is proposed to calculate the levitation force between HTS bulk and permanent magnet, which is validated by way of experiment. In order to improve the usage ratio of permanent magnet (PM) railway and enhance levitation force, a novel type HTS Maglev with the three-layer sandwich structure is proposed by way of HTS combination distributed on the upper and below sides of PM railway. Based on force characteristics and UM software, the digital prototype of novel type HTS Maglev is established including a carriage and six suspension frames. The dynamic response of novel type HTS Maglev can be obtained in the case of different running speeds, which can evaluate the running performance. The aim of our manuscript is to provide a feasible method for performance evaluation and some guidance for optimizing the design of train structure.
