Abstract

In order to ensure the reliability of MAGLEV train, it is necessary to analyze the electromagnetic phenomena on normal and abnormal operations. This report describes the electromagnetic analysis of the abnormal operations, and the comparison between the analysis and experiments. The wire-segments-model analysis makes it clear that the largest electromagnetic force acts to the superconducting magnet (SCM) when an armature coil is short-circuited. On the other hand, the finite element analysis shows the magnetic field is almost shielded by the aluminum plate of vacuum vessel, and only part of lateral force directly acts to the SC coil. These analytical results show good agreement with the experimental results.
