Abstract

Abstract

Based on the ignition experiment of HMX-based PBX explosive with long tube and strong constraint condition, numerical simulation is carried out by adopting the evolution growth model of explosive explosion reaction and multi-material arbitrary Lagrangian-Eulerian algorithm. The influence of ignition mode on the evolution law of explosive reaction is analyzed, and the characteristic image of explosive reaction evolution process under weak impact ignition condition is also obtained. Phenomenological model and numerical simulation method of PBX explosive ignition experiment under strong constraint conditions are constructed for two ignition modes of black powder and detonator, respectively. The characteristic images of explosive column reaction evolution process in steel pipe are obtained by numerical simulation, and the expansion process of cylinder shell is in good agreement with the experimental result. The study shows that there are great differences in the evolution process of explosive reaction under different ignition modes. If the detonator is used for ignition, the detonation reaction of PBX explosive will occur in a few microseconds; when the black powder is used for ignition while the long tube is strongly constrained, the PBX explosive will change from slow combustion to violent explosion in a few milliseconds. With the cracking and disintegration of the shell, the pressure in the tube will drop sharply, inhibiting the transition to detonation behavior, so the whole reaction evolution process under this ignition mode can be divided into four stages. The combustion propagation on the surface of explosive column near the tube wall takes precedence over the matrix reaction in the center of explosive column, which is an important feature of the evolution process of non-impact ignition reaction. The characteristic image and physical quantity curve obtained in this study reflect the evolution law of explosive reaction under the condition of weak impact ignition, which has important value for deepening the understanding of the hazard risk of explosive charge after accidental ignition.
