摘要: 通过对凝聚态炸药爆轰产物JWL状态方程的研究,提出了一种确定JWL状态方程参数的拟合法,即利用律状态方程来拟合JWL状态方程参数。这种新方法不需进行圆筒试验,与现有方法比较,具有经济、安全、方便、准确的特点。利用这种方法拟合确定了4种常用炸药TNT、C-4、PETN、HMX的JWL状态方程参数,通过与圆筒试验法得出的JWL状态方程p-V曲线进行对比,证明拟合法具有较高的精度,完全可以满足计算爆炸力学的应用。Abstract: By investigating the JWL equation of state of detonation products of condensed explosive, we present a method to determine JWL parameters by fitting. This approach does not require cylinder test and is more economical, secure, convenient and accurate than existing methods. Using this method, four kinds of common explosive, e.g., TNT, C-4, PETN and HMX have been studied. By comparing to the p-V curve of JWL equation of state given by cylinder test, we showed that the fitting has a high precision and meets the need of explosion mechanics application.
