Equivalent pulse parameters of massive conductors
Formula for calculating equivalent pulse parameters of massive conductors subject to adiabatic heating and nonlinear magnetic properties of surface layer at diffusion of plane one-dimensional electromagnetic wave into conducting half-space have been obtained. Equivalent parameters (thickness and temperature of surface layer, magnetic field pressure and heat loss power, resistance and inductance) are accepted as averaged and constant ones at action of pulse voltage of magnetic field at conductor surface. This pulse form is approximately taken into account by its duration, mean square value and number of positive and negative half-waves. Nonlinear magnetic properties of ferromagnetic conductor are taken into account by power law for its magnetization curve. Reliability of the obtained formulas is confirmed by examining individual cases for nonferromagnetic conductors and computed dependences for magnetic permeability of structural steel.
