含能破片冲击引爆屏蔽炸药研究
Initiation of Shielded High Explosive Impacted by Energetic Fragment
摘要
Abstract
Based on the one-dimensional shock wave theory and the Wasley's shock initiation energy criterion, the process of energetic fragment impacted shielded high explosives is theoretically and numerically analyzed. Fragment styles, fragment sizes and shielded plate thicknesses are considered respectively. The results show that the critical initiation velocity of the steel shell fragments is larger than that of the aluminum shell fragments, and with the increase of the diameter of energetic materials and the decrease of the shielding, the critical velocity decreases. The theoretically calculated results agree well with those of the corresponding numerical simulation. The different damage mechanism of energetic fragments and inert fragments is found. The damage mechanism of inert fragments is a kinetic energy of impact, but that of the energetic fragment is an explosive chemical reaction energy. The explosive chemical reaction energy is caused by impacted shock waves.关键词
