A Direct Coupled Field-Circuit-Movement Finite Element Method for Modeling EMS-MAGLEV System

摘要

A new 2D transient finite element algorithm for the performance analysis of magnetically levitated vehicles of electromagnetic type is proposed in this paper. The algorithm incorporates external power system and vehicle's movement equations into FE model of transient magnetic field computation directly. The eddy current induced by movement is calculated by using upwinding technique. Using the proposed modeling method, the factors affecting levitation and propulsion forces can be easily investigated. Through computations of an EMS-MAGLEV system, it is shown that the algorithm gives reasonable results.
