Study on the Damage of Earth Penetrator’s Charge Weight and Depth of the Burst Point to the Runway

Abstract:

In order to explore earth penetrator’s effective destruction to the runway, using numerical simulation as the main means, and combined with some experimental data, a study on the intrinsic connection between series of charge weight, different depth of the burst point and damage area of the runway (blasting crater area) is carried out. The results shows that: for the same charge weight of earth penetrator, there is an optimum depth of the burst point (best penetration detonation depth), and the law which is got from numerical simulation is consistent with the experimental one, which indicates that the material model and calculation parameters of numerical simulation are reasonable, the numerical simulation can replace some research experiment and accelerate research progress.
