| 摘 要： | 针对高温超导磁悬浮交通应用,提出了一种有别于目前常用的仅通过车载高温超导块材与永磁轨道间的磁斥力实现悬浮的混合悬浮,该悬浮方式通过车载永磁体与永磁轨道的作用为悬浮系统提供导向力,由于避免了磁滞效应而使导向可回复区间增大,进而提高系统的导向能力,有助于增大系统的曲线通过与抗干扰能力,同时永磁轨道下部空间磁场的利用也进一步提高了系统的悬浮能力。基于系统静态刚度的计算,现有高温超导磁悬浮系统双轨每米的悬浮重量仅为混合悬浮的40%,可回复导向力不到混合悬浮中车载永磁体与永磁轨道间稳定导向力的70%。混合悬浮为高温超导磁悬浮的重载应用提供了一种途径。

| Abstract: | High-Tc superconducting maglev exhibits a huge prospect in the tranportaion and energy field due to its inherent stability. Aiming at the application in the transportation, a hybrid maglev, which is different from the present one realized just by the magnetic repulsion force between the on-board bulk high-Tc superconductor (HTSC) and permanent magnet guideway (PMG), is reported. The guidance force of this kind of maglev type can be provided by the interaction between the on-board permanent magnet and PMG, a... |
