NUMERICAL ESTIMATES OF CURRENTS AND FORCES IN LINEAR TOOLS OF THE MAGNETIC-PULSE ATTRACTION OF METALS. PART 1: LOW ELECTRICAL CONDUCTANCE METALS
Keywords:linear tool for eliminating dents in sheet conductors, intensive penetration of the field into metals with low electrical conductance, magnetic-pulse attraction of conductors with unidirectional currents
AbstractPurpose. The electrodynamics processes study in the linear tools of magnetic-pulsed attraction, the final result of which should be the physics-mathematical dependencies for the characteristics of the flowing processes, under the conditions of intensive penetration in metal of acting electromagnetic fields, as well as numerical estimates of these processes main characteristics. Methodology. To carry out research, we used the fundamental statements of the electromagnetic field theory and the mathematical simulation with help of the standard codes from the Wolfram Mathematica package. Results. The functional dependencies for the space-temporal distributions of the currents and forces excited in the linear tools of magnetic-pulsed attraction under intensive penetration of the acting electromagnetic fields through the tool's conducting construction elements are used for the numerical estimates. From the calculation results it follows that from a physical point of view, the cause of the increase in attractive forces while decreasing the operating frequencies can be considered the intensification of penetration processes of the excited fields, which leads to increasing the magnetic pressure from the outside. Thus, the transition to low operating frequencies of the exciting currents can significantly increase the efficiency of the magnetic-pulsed attraction of the sheet metals with the linear tools. Originality. It was firstly determined that from the physical point of view, the reason for the increase in attractive forces with a decrease in operating frequencies can be considered the intensification of penetration processes of the excited fields, which leads to increasing the forces of magnetic pressure on the conductors from side of their external surfaces. Practical value. A usage of the obtained results will allow creating new, more efficient linear tools of magnetic-pulsed attraction of the low-electrical conduction sheet metals operating under conditions of intensive penetration of the electromagnetic fields being excited.
