Abstract

To study the shock wave initiation characteristics of 2,4,6-trinitrotoluene (TNT) under different charging types, the shock wave pressure and shock wave attenuation of standard Pentolite explosives under different diaphragm thicknesses were quantitatively studied using the ion probe method. The gap tests of three explosives were carried out, including pressed TNT without restraint, pressed TNT with steel pipe restraint, and cast TNT with steel pipe restraint. The shock wave initiation pressures of TNT under the three different conditions were compared. Moreover, combined with the numerical simulation technology, the critical initiation pressure and the pressure cloud diagram of the gap test of TNT were obtained, and the dynamic change process of the shock wave in the diaphragm was acquired, which was difficult to measure in the experiments. The results showed that the critical initiation pressure of pressed TNT was significantly lower than that of cast TNT and that restraint can reduce the measured critical initiation pressure of TNT under certain conditions. Therefore, the research results may provide a basis for the damage range of TNTs with different charging types and the determination of the safety protection distance of shock wave initiation.
