摘要：

A hybrid maglev vehicle using permanent magnets and high temperature superconductor (HTS) bulks is presented. Its guideway is composed of permanent magnets and soft iron. The HTS bulks provide partial levitation force and guidance force, and the onboard permanent magnets provide additional levitation force. Firstly, the levitation force of a single permanent magnet and a single HTS bulk over a permanent magnetic track is studied, the surface magnetic flux density of which is up to 1.2 T. Secondly, both levitation force and guidance force of two arrays of permanent magnets and HTS bulks are studied. Results show that the hybrid maglev vehicle using permanent magnets and HTS bulks has larger levitation force and stiffness. (C) 2002 Elsevier Science B.V. All rights reserved.
