摘要: 对以TATB为主的钝感炸药JB-9014进行了25 mm和50 mm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。Abstract: This article reports the results of two kinds of cylinder test of the insensitive high explosive JB-9014 which consists mainly of TATB, with diameter of 25 mm and 50 mm, respectively. By measuring R(t) the expansion history of the TU1 tube driven by detonation products, we have done some comprehensive analysis and 2D numerical simulations for the cylinder tests, to evaluate the ability of doing work and the similarity of cylinder test. By using 2D fluid dynamic numerical simulation, we obtained the parameters of JWL equation of state for JB-9014. The numerical simulation for 2D slipping detonation driven experiment of JB-9014 shows that the parameters of JWL equation of state derived from our experiments and numerical simulations are reliable and with high precision.
