炸药破甲威力与爆轰参数之间定量关系的探讨

探讨了炸药的破甲威力与爆轰参数之间的关系，发现在一定计算精度范围内，炸药的破甲威力与爆速Ｄ的关系比较复杂，而与爆压Ｐ的关系相对比较简单且具有较高的计算准确度，据此提出，爆压Ｐ与破甲深度ｈ、与破孔体积Ｖ之间的定量关系式。对单质炸药和混合炸药的计算结果表明，计算值与实验值的一致性令人满意。根据这一定量关系，可以确定提高炸药破甲威力的两条件途径，一是提高炸药的爆压，即提高炸药的能量，二是通过设计新型装药结构，提高炸药能量的利用率，应用本文定量关系，不仅能够预测炸药的破甲威力，而且对于寻求具有优良破甲威力的炸药及设计新型装药结构具有一定的参考价值。

Studies on the Quantitative Relation between the Penetration Performance and Explosive Properties

The relation between explosive properties and penetration performance was studied in this paper, and two equations were proposed to calculate the penetration depth h and penetration volume V from the detonation pressure P. The calculated results showed that the calculated values of h and V for explosives and mixture explosives were in good agreement with the experimental data,the mean absolute deviations were 5.64 mm and 1.53cm 3 respectively,which were close to experimental error range.Not only can the quantitative relation developed in thhis paper be used to calculate the pentration depth h and penetration volume V from the detonation pressure P ,but it can help to develop new explosives.
