摘要: 提出通过水中实验确定炸药的水中爆轰产物JWL状态方程参数的方法；选择PBX-01高能炸药进行水中实验，利用ANSYS/LS-DYNA程序建立炸药的水中实验模型，将实验结果与数值计算结果进行对比，确定PBX-01炸药水中爆轰产物的JWL状态方程参数。研究结果显示，圆筒实验确定的JWL参数在反映炸药水中爆轰产物的膨胀状态时有所不足，水中实验确定的JWL状态方程参数能够更准确地描述PBX-01炸药水中爆轰产物的膨胀过程，因此对水中爆炸的研究需要通过水中爆炸实验建一套状态方程参数。Abstract: A method was raised by taking out the underwater explosion test to determin the JWL state equation parameters of detonation products. The PBX-01 explosive was applied and a calculating model of underwater explosion test was established by using ANSYS/LS-DYNA program. The JWL state equation parameters of detonation products for PBX-01 explosive were determined according to the comparison of the experimental and numerical results. Parameters determined by underwater explosion test and cylinder expansion test were used for detonation products driving water test. The results show that the underwater explosion test numerical simulation is accordant better in initial stage. Specially appointed patameters need to be established in the underwater explosions.
