Numerical simulation of forming lines by means of a two-dimensional rectangular grid of sections of uniform long lines (by the example of an C-300 generator)

摘要

A metod for numerical simulation of forming lines is described. The method is based on piece-difference approximations to the wave equation in the form of a two-dimensional rectangular grid of sections of uniform long lines. Computational errors are estimated as functions of the number of grid nodes and the ratio of the characteristic time of the signal source to the line length. An example of the numerical simulation of the forming part of an C-300 generator, which was developed and started at the Kurchatov Institute, is considered. The rms deviation of the pulsed output voltage of the C-300 generator from the theoretical pulses calculated using one- and two-dimensional models is 12 and 3.8%, respectively.
