| 摘 要： | 为了获得标定未反应PBXC10炸药(Jones-Wilkins-Lee)JWL状态方程参数的基础数据,提出了一种获得未反应炸药冲击Hugoniot关系的方法,即基于冲击起爆实验测得的PBXC10炸药中不同拉格朗日位置的压力历史,假设冲击波前沿炸药未发生化学反应,并利用冲击波阵面前后的动量守恒关系,获得未反应PBXC10炸药的冲击Hugoniot关系. 将该冲击Hugoniot关系外推到爆速,得到PBXC10炸药的冯诺依曼峰值压力,发现该峰值压力与PBXC10炸药的CJ (Chapman-Jouguet) 压力之比在合理范围内.

| Abstract: | In order to obtain the basic data for determining the parameters of the JWL equation of state of unreacted PBXC10, an approach which was based on the pressure histories at different Lagrange positions in a PBXC10 explosive obtained by the shock initiation experiment was proposed to obtain the unreacted shock Hugoniot relationship for the explosive. In the meantime, the explosive in the front of the shock wave was nonreactive and the momentum conservation before and after the shock wave was utilized, so that the shock Hugoniot relation for the unreacted PBXC10 explosive was obtained in this paper. The von Neumann spike pressure of the PBXC10 explosive was given after extrapolating this relation to the detonation velocity to yield. It is found that the ratio of this spike pressure to the Chapman-Jouguet pressure of the PBXC10 is in a reasonable range. |
