摘要

摘要: 对钝感高能炸药JB-9014的爆轰产物JWL状态方程进行了深入研究。利用改进的圆筒试验技术，得到了筒壁膨胀的质点速度、位移和加速度的实验结果；通过解析分析和曲线拟合相结合的方法，确定了爆轰产物JWL状态方程参数；采用ANSYS/LS-DYNA3D程序进行了数值模拟，并与实验结果进行了对比和分析，验证了状态方程参数的适用性。

Abstract: The JWL equation of state of detonation product for insensitive high explosive JB-9014 was further studied. The particle velocity, displacement, and acceleration of the cylinder wall were obtained from the modified standard cylinder test. The parameters of JWL equation of state were derived from analytical analysis and non-linear curve fit. The cylinder expanding process was numerical simulated using the ANSYS/LS-DYNA3D. The simulation results are consistent with the experimental results, which indicate that the parameters of JWL equation of state derived in this work are suitable and reliable.
