Calculation of the 3D Non-linear Eddy Current Field in Moving Conductors and its Application to Braking Systems

摘要

This paper presents a complete FE formulation for the calculation of 3D non-linear eddy current fields with ferromagnetic moving conductors. The formulation is realized by using the A, V-A formulation in combination with the Coulomb gauge. To consider non-rectangular shapes of geometries tetrahedral elements were employed. The computation procedure is applied to an eddy current braking system of a high velocity train and the resulting braking forces are compared to measurements.
