[Abstract]:Aiming at the present situation of safety protection in ammunition stacking storage process in field environment, this paper studies the anti-explosion performance of portable explosion-proof wall under the action of blast wave, fragment and shaped jet in field environment. In order to provide some reference for our military exercise training and ammunition stacking safety protection in actual combat. The main research contents are as follows: (1) the background and significance of studying the anti-explosion performance of portable explosion-proof wall in field environment are expounded, and the formation and action principle of three kinds of damage elements related to anti-explosion research of explosion-proof wall in field environment are analyzed. In this paper, the condition of ammunition explosion and the initiation criterion are summarized. (2) through the similarity rate of explosion, the scaling model is established, and the diffraction law of explosion shock wave under the action of portable explosion-proof wall is studied, and the different charge quantity and different size thickness are studied. The influence of different explosion distance on the distribution of diffracted overpressure behind the wall is obtained, and the distribution law of the diffracted overpressure behind the wall is obtained under different conditions. On the basis of the above simulation results, the dynamic simulation of the ammunition behind the wall under the action of explosion load is carried out. The pressure curve of the projectile under explosive load is obtained. When studying the penetration resistance of the portable explosion-proof wall, the static explosion simulation of the 130mm explosion-killing grenade is carried out, and the mass distribution of the fragmentation field is obtained by numerical simulation. On the basis of the static explosion simulation results, the penetration resistance of explosion-proof walls with different media and thickness is simulated numerically. The penetration depth of the fragment to the explosion-proof wall with different filling media and different thickness is obtained. Finally, the influence of residual velocity of fragments on the safety of ammunition stacking is analyzed. The effect of filling different media and different thickness of portable explosion-proof wall on reducing the velocity of the rod jet is obtained. The residual velocity of the rod jet passing through the wall is analyzed.
