【摘要】 美国Magplane磁悬浮列车方案有两种,一种是速度在500km/h的超导方案,另一种是速度约250km/h的永磁方案。与其他高速磁悬浮列车相比,美国高速磁悬浮列车方案使用了永磁悬浮,使悬浮气隙达5￣15cm,这样可以大大降低轨道土建工程施工的精度要求,并且该系统使用电磁道岔,改变了多数磁悬浮列车系统使用机械道岔,占地面积大,操作不方便的缺点,从而该方案具有造价低、原理简单、悬浮间隙大、起浮速度低的优点。文章从原理、创新、存在问题等方面对美国Magplane磁悬浮列车永磁方案进行了较详细的介绍。更多还原

【Abstract】 The Magplane has two schemes. One is superconducting scheme with maximum speed about 500km/h, the other is permanent magnetism scheme with maximum speed about 250km/h. Comparing with other Maglev trains, Magplane has the advantages of using permanent-magnet and the electromagnetic switch which require less precision and space at project construction. Magplane is cheap and simple in principle, it can take off at very low speed and levitate with big air gap. The innovation, the principle and the problems of Magplane are represented in detail in this article.更多还原
