| Popis: | Shallow-buried explosion is a typical working condition of ammunition. Studying the overpressure propagation law of air shock wave in shallow-buried explosion is helpful to completely characterize the ammunition power in actual combat. In this paper, a numerical model of shallow-buried explosion of cylindrical charge based on Euler method is established in the framework of simulation software AUTODYN, which simulates the formation process of crater when cylindrical charge is initiated under the conditions of different charge amount and different buried depth, and analyzes the propagation law of explosion shock wave in the air. The following conclusions are drawn: compared with the mass of charge, the depth of burial has more influence on the surface air shock wave. According to the simulation data, the empirical formulas related to the peak overpressure of shock wave and the charge, buried depth and horizontal detonation center distance are fitted. |
