摘　　要：本文主要研究超导磁悬浮系统中超导块材与永磁导轨之间的相互作用力,通过浸于低温容器中的超导块材与三磁峰轨道之间不同排布方式的实验,测试不同悬浮间距的悬浮力,以及在一定场冷距离下超导块材在三磁峰轨道上方不同水平位移段的导向力。结果表明,悬浮间隙越大,超导块材中心与三磁峰轨道中心水平偏移越小,悬浮力越大;在一定悬浮间距下,超导块材与三磁峰轨道之间水平位移越大,导向力越大。This paper mainly studied the interaction force between superconduction blocks used for superconducting magnetic levitation system and permanent magnetic guideway(PMG). Experiments were designed to study levitation force and guiding force. The levitation characteristics of several different superconducting blocks arrangements immersed in cryogenic vessel in the maglev system were studied in this paper through experiment to seek the best arrangement. The characteristics of guiding force was studied when superconducting blocks was at different horizontal sections above three peaks PMG at certain cooling distance. The results show that the larger the levitation gap, the smaller the horizontal offset between superconducting blocks center and the three peaks PMG center, and the larger the levitation force;in certain levitation distance, the greater the horizontal displacement between the superconducting blocks and the three peaks PMG, the greater the guiding force.
