摘要
在PBX炸药冲击损伤和冲击起爆实验的基础上,采用拉格朗日分析方法对损伤炸药的化学反应速率方程进行整体标定,并对损伤炸药的冲击起爆过程进行了数值模拟.结果表明,损伤炸药冲击波感度提高,得到了损伤炸药化学反应速率方程相关参数的变化规律.
Reaction rate equation is the key shock initiation. This equation is calibrated damage and shock initiation experiments. damaged explosives. Relations between the out i.n the simulation of the process of damaged explosives＇ by Lagrange analysis on the basis of the results of impact Their results showed that the sensitivity increased in degree of damage and reaction rate equation were brought out.
