摘　　要：介绍了３种用于永磁悬浮车的永磁悬浮机构。一种车体重心在悬浮机构之上，另两种车体悬挂在悬浮机构之下。根据永磁体斥力与吸力的基本特性，从力学平衡与稳定性的角度，对３种永磁悬浮机构进行了研究。分析表明将永磁体的斥力和吸力合理组合能够将车体悬浮起来。在３种永磁体悬浮结构中，斥力和吸力共同作用下的悬挂式悬浮机构可实现静态稳定悬浮。Three mechanisms, magnetically levitated by permanent magnets are introduced and analyzed in respect of their balance and stability based on the nature of attraction and repulsion by permanent magnets. The barycenter of the vehicle body is above the magnetic suspension mechanism in one mechanism, below it in the another two. The analysis shows that, among the three mechanisms presented in this paper, the suspension mechanism combining magnetic attraction and repulsion can be statically stable, while the other two can not.
