A Modified Finite Element Model for Electromagnetic Tube Compression Process

Abstract:

This paper presents an approach for modification a FEM simulation of electromagnetic tube compression process which has been presented by Mamalis. Electromagnetic free compression of a tube inside a coil has been simulated by using elements with coupled DOFs of electrical and magnetic potentials and displacement components. Mamalis's simulation results show a degree of disagreement with experimental results. In the present work, the coil has been modeled as separate parallel rings and a new correction factor has been determined for the current load applied on the coil. Comparison between simulation and experimental results shows a good agreement at the middle of workpiece with a reasonable error at workpiece ends.
