| 摘 要： | 为了研究2个装药不同箱体结构内部同时爆炸的破坏效应，利用模拟箱体结构，进行了相同质量TNT装药在单箱体和4层箱体内部爆炸试验，分析了装药质量和箱体容积的匹配关系以及双装药布放位置对4层箱体破坏效果的影响. 结果表明，整体装药单层箱体内部爆炸时，箱体撕裂、抛掷严重，结构整体毁伤效果差；以箱体的破坏数量为基准，2个装药(每个装药的质量为整体装药的1/2)在双箱内部爆炸的毁伤效果都优于相同质量整体装药单箱内部爆炸. 装药位置导致的能量叠加和扩散对多箱体的毁伤效果影响很大，整体装药的较佳爆炸位置为中间箱体，双装药的较佳爆炸位置为中间的相邻箱体或隔箱，相隔一个箱体破坏效果最好.

| Abstract: | To study the damage effect of simultaneous explosion of two charges in different cabin structure, some explosion tests were carried out for the condition, TNT charges with the same mass, explosion in single and four cabins with simulated cabin structure. The tests were arranged to analyze the matching relationship between charge mass and cabin volume, and the influence of charges location on the damage effect of four layer cabins. The results show that group charge detonation in single layer cabin can result in the serious tearing and throwing, but the damage effect of the whole structure is not remarkable. According to the damage quantity of cabin, the damage effect of two charges (the mass of each charge equals 1/2 mass of group charge) in two different cabins is better than that of group charge with the same mass in one layer cabin. The energy superposition and diffusion caused by the charge position have a great influence on the damage effect of multi layer cabins. The better explosion position of the group charge is the middle cabin, and the better explosion position of two charges is the adjacent cabins or compartment in the middle, and the damage effect of one compartment is the best. |
