Evaluation of the efficiency of the process of electromagnetic forming of small-diameter tubes

This work presents results of evaluation of the efficiency of the process of pulse-magnetic forming of small-diameter tubular billets according to the scheme with direct passing the current, including the results of computer simulation of the process using the LS-DYNA software package and its experimental perfecting. The purpose of this work is to determine the efficiency of the process of pulse-magnetic forming of small-diameter tubular billets according to the scheme with direct passing the current through the billet. As a result of the research, it is established that the scheme under consideration and the proposal technological solutions for its implementation can be used in the manufacture of a rather wide range of tubular parts of various diameters. This removes the existing restrictions when pulse-magnetic forming of small-diameter pipes according to the traditional scheme and LS-DYNA contributes to a significant expansion of the fields of application of the pulse-magnetic technologies.
