含铝炸药爆炸能量预估

摘要

In order to predict the explosion energy of aluminized explosives, a non-ideal detonation energy predicting mode after theoretical analysis was built and the software by matlab software, numerical iteration and numerical preparation was developed. The software is suitable for aluminized explosive C-J pressure, C-J velocity predicting of some common aluminized explosives such as H-6, HBX-1 , Alex 20, Alex 32, Tritonal and Torpex. The detonation parameters and explosion energy calculated by the software agree well with empirical results and all of the deviations of aluminized explosives are less than 8% , which is useful for the explosion energy prediction of aluminized explosives.%为了预估含铝炸药爆炸能量,分析了非理想爆轰能量预测模型,利用matlab软件、迭代计算方法、平衡常数方法和数值逼近原理编制了数值计算软件.利用本软件计算了常用含铝炸药H-6、HBX-1、Alex 20、Alex 32、Tritonal及Torpex的C-J爆压、C-J爆速等相关参数,与已有实验值吻合较好.计算结果表明,利用本软件所计算的爆温和爆热结果与以往经验公式计算结果吻合较好,爆热的相对误差小于8％,故适合于含铝炸药的能量预测.
