摘　　要：为探讨RD X基高聚物黏结炸药在小尺寸下爆轰产物的状态方程,采用两种直径(Φ10 m m和Φ25 m m)的圆筒试验研究了RD X基高聚物黏结炸药的做功能力,获得了圆筒壁膨胀位移、速度与时间的关系;利用非线性有限元动力学程序A n sy s/L s-D yn a,对炸药的圆筒实验进行了数值模拟;通过与实验结果相比较,得到了RD X基高聚物黏结炸药爆轰产物JW L状态方程参数。In order to study the equation of state（EOS） of the detonation products of RDX-based PBX at small scale,cylinder tests were carried out to identify the power of RDX-based PBX with density of 1.65 g·cm-3.The copper tubes with diameter in 10 mm and 25 mm were used.The scale of the wall expansion and the velocity were measured.The cylinder tests were numerically simulated by nonlinear finite element dynamic program Ansys/Ls-Dyna.The parameters of the JWL EOS for RDX-based PBX were calculated and corrected according to the numerical simulation results.
