含铝炸药爆轰产物JWL状态方程研究

对ＲＯＴ ９０１含铝炸药进行了爆轰产物ＪＷＬ状态方程研究。对ＲＯＴ ９０１炸药进行了２５ｍｍ和５０ｍｍ两种装药直径的圆筒试验，测试了圆筒膨胀过程的Ｒ ｔ关系。由冲击Ｈｕｇｏｎｉｏｔ关系和参考的ＰＯＰ关系拟合了ＲＯＴ ９０１炸药的反应速率。对两种装药直径的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ＲＯＴ ９０１的作功能力和圆筒试验的特性。通过对两种装药直径圆筒试验圆筒膨胀过程的解析分析计算和二维数值模拟，确定得到了ＲＯＴ ９０１含铝炸药爆轰产物ＪＷＬ状态方程参数。

STUDIES ON JWL EQUATION OF STATE OF DETONATION PRODUCT FOR ALUMINIZED EXPLOSIVE

This article reports the results of two sets of cylinder test for the aluminized explosive ROT 901,with diameter of 25mm and 50mm,respectively.By measuring R(t) the expansion history of the T 2Y tube driven by detonation products,we have made analysis and 2D numerical simulations for the cylinder test to evaluate the ability of doing work for this explosive.By using 2D fluid dynamic numerical simulation,we obtain the parameters of JWL equation of state of detonation product for this explosive.
