摘要
为了提高混合炸药爆热计算方法的准确度和适用范围,在盖斯定律的基础上,结合非理想炸药的爆轰机理和爆轰产物生成规律,对金属燃料的反应度以及F、Cl等元素生成产物的顺序做出假设,提出了一种适用于预估混合含铝炸药爆热的计算方法。利用该方法和传统的经验法分别计算了C_(a) H_(b)N_(c)O_(d)Al_(e)类简单体系的含铝炸药以及C_(a)H_(b)N_(c)O_(d)F_(f)Cl_(k)Al_(e)Mg_(y)类复杂体系的含铝炸药的爆热,并与恒温法的测试值进行比较。结果表明,改进后的方法计算精度大幅提高,相对误差的平均值和方差均小于5%。对于铝粉含量不同的混合炸药,影响其爆热计算结果的主要因素不同,当炸药中铝粉含量逐渐增加时,AlN对爆热计算值的影响逐渐增大。
In order to improve the accuracy and applicable scope of the calculation method for the explosion heat of mixed explosives,we made assumptions about the reactivity of metal fuels and the order of F,Cl and other elements to produce products by combining the detonation mechanism of non-ideal explosives and the law of detonation product generation on the basis of Guess’s law.A calculation method suitable for estimating the explosion heat of aluminized explosives was proposed.After that we used this method and the traditional empirical method to calculate the explosion heat ofC_(a) H_(b)N_(c)O_(d)Al_(e) explosives and C_(a)H_(b)N_(c)O_(d)F_(f)Cl_(k)Al_(e)Mg_(y) explosives comparing with values measured by the method of constant temperature.The results show that the calculation accuracy of the improved method is greatly improved,and the average and variance of the relative error are both less than about 5%.For mixed explosives with different aluminum powder content,the main factors that affect the calculation results of the explosion heat are different.And when the content of aluminum powder in the explosive gradually increases,the influence of AlN on the calculated explosion heat gradually increases.
