【摘要】：为研究RDX基PBX炸药的做功能力并确定其爆轰产物的JWL状态方程参数,对RDX基PBX炸药和TNT炸药进行φ50mm标准圆筒实验,获得了圆筒膨胀位移和速度的时程曲线,对比得出RDX基PBX炸药的做功能力明显高于TNT炸药;基于能量守恒对实验数据进行非线性拟合,得到2种炸药爆轰产物的JWL状态方程参数。TNT炸药的拟合参数和通过AUTODYN软件计算得到的结果符合较好;将采用上述方法得到的RDX基PBX炸药爆轰产物JWL状态方程参数用于数值模拟,计算结果与实验值吻合较好,符合数值模拟标定JWL状态方程参数的要求。
[Abstract]:In order to study the work capacity of RDX based PBX explosives and determine the JWL equation of state parameters of their detonation products, the 蠁 50mm standard cylinder experiments of RDX based PBX explosives and TNT explosives were carried out. The time history curves of the expansion displacement and velocity of the cylinder are obtained. The results show that the work capacity of the RDX based PBX explosive is obviously higher than that of the TNT explosive. Based on conservation of energy, nonlinear fitting of experimental data is carried out. The JWL equation of state parameters of two detonation products. The fitting parameters of TNT explosives are in good agreement with the results calculated by AUTODYN software. The JWL equation of state parameters of detonation products of RDX based PBX explosives obtained by the above method are used in numerical simulation, and the calculated results are in good agreement with the experimental values. It accords with the requirement of numerical simulation to calibrate the parameters of JWL equation of state.
