Abstract

Purpose. The purpose of the present work is substantiating workability of the linear tools of the magnetic-pulse attraction of thin-walled sheet metals with high electrical conductance, the principle of which is based on the force interaction of two conductors with unidirectional currents during intensive penetration of the acting electromagnetic fields. Constructively, one of these conductors in the linear tools is the so-called main current lead (an analog of the inductor in EMF) and the second one is the part of the sheet metal which has to be deformed. Methodology. For numerical estimates the analytical dependences are obtained with help of the methods of electromagnetic field theory as well the standard programs from the Wolfram Mathematica package used. Results. The fulfilled calculations illustrate the amplitude-temporal dependences for the excited currents and forces under the demanded decrease of the operating frequencies of the acting electromagnetic fields. The efficiency of the linear magnetic-pulse tools is based on the excitation of the mutual attraction forces of conductors with low-frequency unidirectional currents. Originality. By the example of aluminum, which is the main raw material in modern aviation and automotive industry, it has been found that for processing the metals with high electrical conductance demand a significant decreasing operating frequencies, what is necessary for intensifying the penetration processes of acting fields and, accordingly, for exciting the real attractive forces. Practical value. The results of the work allow formulating the based recommendations for the creation and practical application of the linear magnetic-pulse attraction tools for the progressive technologies of restoring the damaged areas of bodies coatings from the thin-walled sheet metals with the high specific electrical conductivity.
