Abstract: The superconductor/guideway relationship is similar to the wheel/rail relationship of the highspeed railway, which is of paramount importance in maglev system. In the superconductor/guideway relationship, the levitation and guidance characteristics of high-temperature superconducting (HTS) materials directly impact the dynamics of HTS maglev vehicles. In light of this, this paper investigates the levitation and guidance characteristics of the superconductor/guideway relationship affected by different external factors. First, establish a two-dimensional superconductor/guideway relationship model considering multi field coupling. Second, propose a calculation method considering the interaction between superconductor and guideway to simulate the forced lateral and vertical vibrations as well as the longitudinal motion of dewar. Then, an equivalent three-dimensional mechanical model of superconductor/guideway relationship that takes into account the multi field coupling effects of electricity, magnetism, thermality, and force is established. Finally, focusing on the impacts of dewar's working height, magnetic field's irregularity, and HTS bulks' working temperature, the dynamic characteristics of superconductor/guideway relationship in motion can be studied. This paper employs the mechanical model of equivalent three-dimensional superconductor/guideway relationship established to analyze the impacts of three external factors on levitation and guidance characteristics under multi-field coupling, providing effective references for the dynamic response of HTS bulks' levitation and guidance characteristics.
