摘要

摘要: 为了解决现行爆炸复合装药方式落后及炸药爆炸的能量利用率极低的问题，使用了一种保证装药质量的蜂窝结构炸药，并将该蜂窝结构炸药应用于一次起爆可复合二块复合板的双面爆炸复合技术。进行了7 mm厚的蜂窝结构炸药用于3 mm厚的不锈钢板和16 mm厚的Q235钢板的双面爆炸复合实验；并计算得到了复板碰撞速度的上下限及2组实验中复板的碰撞速度。由于受到蜂窝材料和双面复板的多向约束，炸药的临界厚度显著降低，乳化炸药在5 mm厚度时仍可以稳定爆轰。研究结果表明：和现行的单面爆炸复合相比，在复合相同数量复合板的情况下，采用蜂窝结构炸药的双面爆炸复合技术中，炸药的使用量节省了77%，炸药的能量利用率得到显著提高；计算与实验结果一致性较好。

Abstract: In order to resolve the current issue about the backward method of charge and low energy efficiency of explosives, a kind of explosive with the structure of honeycomb is used to ensure the quality of the charge and is applied in double sided explosive cladding in which two plates can be combined in one explosion. A double sided explosive caldding experiment of stainless steel plates with the thickness of 3 mm and Q235 steel plates with thickness of 16 mm is carried out by using the explosive with the thickness of 7 mm. The explosive cladding window of the collision velocity is calculated as well as the collision velocity in two groups of the tests. The critical thichness of the explosive is remarkbly reduced with the explosive astricted by the honeycomb structure and the plates. The emulsion explosive with the thickness of 5 mm detonates stably. The result shows that, compared to the existing explosive cladding method, the consumption of explosives by using this method is reduced by 77% in the case of cladding the same number of combination plates. The calculation prefigure explosive cladding of stainless steel/Q235 steel exactly.
