| 摘 要： | 采用AUTODYN计算软件,对含铝炸药与理想炸药水中爆炸能量输出结构进行了数值模拟,讨论了人工黏性对计算结果的影响,对冲击波压力历程进行了对比分析.结果表明,含铝炸药PBXN-105水中爆炸时由于铝粉的二次燃烧放热,能够在较远距离处保持较大的冲击波能,作功能力高于理想炸药PBX9010.含铝炸药水中爆炸能量输出结构的数值模拟可以为炸药的配方设计提供一定的依据.

| Abstract: | Numerical simulation of energy output structure for an aluminized explosive and an idealized explosive in underwater explosion has been performed with AUTODYN software. Influence of artificial viscosity on simulation results has been discussed and comparisons of histories pressure profiles have been made. Aluminized explosive PBXN-105 can keep larger shock energy than PBXg010 in far-field because of combustion of aluminum powders. Numerical simulation of energy output structure for aluminized explosive can provide theoretical guide for designs of underwater explosives. |
