含铝炸药JWL状态方程参数的确定

摘要

The JWL equation of state with diameter of 25 mm and 50mm was studied by two sets of cylinder test for aluminized explosive. By using theory analysis and 2D numerical simulations for the cylinder test the parameters of JWL equation of state for two kinds of aluminized explosive were obtained. The result indicates that the acceleration ability for aluminized explosive after detonation is stronger. The acceleration ability and parameters of JWL equation of state relate to the dimension of aluminized explosive.%用圆筒试验研究了Φ25 mm和Φ50 mm含铝炸药的JWL状态方程,采用解析求解和二维数值模拟,得到了两种含铝炸药的JWL状态方程参数.结果表明,压装含铝炸药的后加速能力较强.含铝炸药的加速能力与JWL状态方程参数与尺寸有关.
