摘要
选取26组HMX基混合炸药,通过考察HMX含量、炸药的密度及空隙率与隔板厚度间的关系,对数据进行统计分析,建立了以HMX含量、炸药密度及空隙率为自变量的两个经验数学模型。计算结果表明,HMX基混合炸药大隔板厚度与HMX含量、炸药空隙率的自然对数成显著线性关系;两个经验数学模型拟合优度良好;4组HMX基混合炸药大隔板厚度计算值与试验值的相对误差小于6%。
The 26 kinds of HMX-based composite explosives were selected. Two empirical mathematic models were established through considering the relation of HMX content, density and void ratio of explosive with thickness gap test data by linear regression fit methods. The results show that the large scale gap thickness is significantly linear related to HMX content and natural logarithm of explosive void ratio; the goodness of fit on two empirical math- ematic models is well; the relative error of the calculated results and experimental ones of gap thinkness for four HMX-based composite explosives is within 6 %.
