针对静压药工艺过程中炸药的安全问题，对等静压工艺和普通压装工艺进行数值模拟。建立了等静压和普通压装2种计算模型，采用有限元方法进行了炸药等静压工艺的数值模拟，计算了等静压作用下炸药内部的压力和温度的变化趋势，同时进行普通压装工艺的数值模拟，并将等静压工艺和普通压装工艺进行了对比。研究结果表明：在相同的比压下，等静压工艺中炸药的最大温升和塑性应变均比普通压装工艺小，炸药等静压工艺比普通压装工艺更安全。

In order to study the safety of explosive isostatic pressing, finite element method was used to calculate pressure and temperature of the explosive during the process of isostatic pressing, and the calculation results of temperature rise accorded with experimental results. Numerical simulation of normal pressing was also conducted, and from the comparison of isostatic pressing and normal pressing it can be inferred that both maximum temperature rise and effective strain in the isostatic pressing are less than that in normal pressing, which means explosive isostatic pressing is safer than normal pressing.
