| 摘 要： | In this paper, a modified transient finite element (FE) algorithm for the performance analysis of magnetically levitated vehicles of electromagnetic type is presented. The algorithm incorporates the external power system and vehicle’s movement equations into FE model of transient magnetic field computation directly. Sliding interface between stationary and moving region is used during the transient analysis. The periodic boundaries are implemented in an easy way to reduce the computation scale. It is proved that this method can be used for both electro-motional static and dynamic cases. The test of a transformer and an EMS-Maglev system reveals that the method generates reasonable results at very low computational costs comparing with the transient FE analysis.

| Abstract: | In this paper, a modified transient finite element (FE) algorithm for the performance analysis of magnetically levitated vehicles
of electromagnetic type is presented. The algorithm incorporates the external power system and vehicle’s movement equations
into FE model of transient magnetic field computation directly. Sliding interface between stationary and moving region is
used during the transient analysis. The periodic boundaries are implemented in an easy way to reduce the computation scale.
It is proved that this method can be used for both electro-motional static and dynamic cases. The test of a transformer and
an EMS-Maglev system reveals that the method generates reasonable results at very low computational costs comparing with the
transient FE analysis.
