摘要
爆轰产物的状态方程一直是凝聚炸药爆轰理论研究的重点和难点。为了能够得到带有二次反应的含铝炸药(80%RDX/15%Al/5%wax)Jones-Wilkins-Lee(JWL)状态方程,分别开展了含铝炸药在混凝土中的爆炸试验和圆筒试验;并利用AUTODYN有限元软件,采用数值模拟与试验相结合的方法,根据圆筒管壁的膨胀速度与时间的关系,得到了经典的JWL状态方程参数;同时,根据含铝炸药在混凝土中爆炸形成的漏斗坑半径和深度,确定了铝粉反应速率方程参数,最终得到了带有二次反应的JWL状态方程。这为将来利用数值模拟研究含铝炸药的爆炸性能,提供了重要的参考价值。
The equation of state for detonation products is the key and difficult points of research on the detonation theory of condensed explosives. The explosion experiment of aluminized explosives in concrete and the cylinder tests are performed in order to obtain Jones-Wilkins-Lee( JWL) equation of state with secondary reactions for aluminized explosives( 80% RDX /15% Al /5% wax). According to the relationship between tube wall velocity and time,the parameters of classic JWL equation of state are obtained by means of numerical simulation and experimentation. The parameters of reaction rate equation of aluminum are determined on the basis of the radius and depth of crater. At last,the JWL equation of state with secondary reactions is acquired.
