Consideration of the Magnetic Field Penetration through the Blank Wall in the Processes of Pulse-Magnetic Forming

Abstract

The results of the investigation of the effect of the magnetic field penetration through a blank wall on the necessary parameters of the pulse-magnetic forming are presented in this paper. The purpose of the work is to determine the permissible scope of engineering techniques for calculating the processes of pulse-magnetic forming of thin-walled parts. Process studies include conducting experiments, calculating by engineering methods and computer simulation of the process using LS-DYNA. As a result of the research it has been established that the engineering technique allows calculating the processes with sufficient accuracy at a blank thickness exceeding the value of the penetration depth of the pulse magnetic field into the blank material.
