摘要
对以ＴＡＴＢ为主的钝感炸药ＪＢ－９０１４进行了２５ｍｍ和５０ｍｍ两种装药直径的圆筒试验，测试了ＴＵ１圆筒在爆轰产物驱动下的膨胀过程Ｒ（ｔ）关系。对圆筒试验进行了综合分析和二维数值模拟计算，综合评估了ＪＢ－９０１４的作功能力和圆筒试验的相似性。通过二维流体动力学数值模拟，确定得到了ＪＢ－９０１４炸药爆轰产物ＪＷＬ状态方程参数。经对ＪＢ－９０１４二维平面滑移爆轰驱动试验的数值模拟检验，证明确定的ＪＷＬ状态方程参数是可靠的，具有较高的精度和普适性。
This paper modifies the constitutive equation of the porous materials by introducing a new variable α v instead of α ,which describs the occupation ratio of non zero pressure matrix volume in porous materials.The new equation p=α vF(α vv,E )solves the problem the p α model encountered when it is applied to partially melt porous materials.The result of the numerical simulation shows that this modification is reasonable and feasible,and is of valuable for numerical simulation to porous materials under shock wave loading.
