摘要

摘要: 进行了炸药柱等静压实验，用热电偶测量了药柱压制成型过程中的内部温度，建立了药柱在等静压下的热力耦合模型。对炸药柱保压阶段进行了数值模拟计算，得到等静压条件下药柱内部压力和温度变化，分析了药柱形变，压力和温度分布。结果表明：在等静压下药柱各表面均有明显的向里凹陷的现象，在受力过程中炸药内部温度升高，并存在温差，内部压力分布不均匀。

Abstract: The experiments of cylindrical explosive isostatic pressing were carried out. The internal temperatures in pressed explosives were measured by thermocouples. A thermal/structural coupled model of the explosive isostatic pressing was set up. The numerical simulations of cylindrical explosive were conducted. The calculated pressures and temperatures in explosives were given. The deformations,pressures and temperatures distribution were analyzed. The calculated results indicated that each surface center of the cylindrical explosive was sunken by isostatic pressing. During the isostatic pressing of cylindrical explosive, the internal temperature of the explosives increases, and the temperature and pressure are not uniform.
