| 摘 要： | 根据P.K.Tang等提出的对炸药爆轰产物超压状态方程建模时只对JWL状态方程CJ等熵线中
高压指数项做修正的研究思路,首先给定超压状态下内能等熵线的修正项,再根据热力学定律对内能等熵线
求微分而得到沿压力等熵线的修正项。对JB-9014炸药超压爆轰冲击Hugoniot实验数据和声速实验数据同
时进行拟合,得到了3个JWL状态方程在超压爆轰状态下的修正项,并进行了分析与比较。得到超压修正项
的方法简单,3组超压修正项与P.K.Tang的修正项一样,都能很好地拟合超压Hugoniot数据。在实验数据
范围外,对超压状态下的声速-压力实验数据的拟合精度有所差别。

| Abstract: | Based on P K Tang's opinion that only the high-pressure term of Jones-Wilkins-Lee equation of state(JWL EOS) needed to be modified when used for overdriven detonation,the modified term of the internal energy isentropic curve was presented and the modified term of the pressure isentropic curve was obtained from the differential form of the internal energy isentropic curve by applying the first law of thermodynamics.And three modified JWL equations of state for overdriven detonation products of JB-9014 explos... |
