Annotation:
The article, using modern information technologies (the ANSYS AUTODYN application software), presents a developed methodology for creating a computer model to accurately determine the penetrating action of a shaped charge made of an energy-saturated material of increased power along the depth of a channel in a steel barrier. The influence of the computational grid parameters (1, 2 and 3 cells per 1 mm) of the Euler part of the model on the indicators of the shaped charge breakdown action is comparatively studied. It is shown that when creating a computer model, the computational grid dimension of the Euler part of the model should be 3 cells per 1 mm. This will ensure high accuracy of the calculation (forecast) of the penetration depth and diameter. The computation time will be 3,5 hours. It is found that the cells increase in the computational grid of the Euler part of the model decreases the relative error from 4 to 0 %. The forecast of the value of the penetration depth and the diameter of the steel barrier is clearly demonstrated. The comparative study results of computer modeling and the full-scale experiment are presented.
