| 摘 要： | 建立了液体药受到连续压缩和动态冲击载荷2种情况下的数学物理模型，并用差分格式进行了数值模拟，得到了液体药在受到连续载荷和动态冲击载荷压缩过程中的物理参量变化规律。计算表明，只有机械能转换成内能是不能引起液体发射药着火燃烧的。这对研究液体发射药火炮的射击安全性具有参考意义。

| Abstract: | A mathematical physical model of liquid propellant compressed by impact and continual loads was established, and it was numerically simulated by MacCormack scheme. The physical regularity is obtained in the process of dynamic impact and continual compression. It is calculated that transformation of mechanical energy into internal energy of the propellant doesn't result in burning or explosion of the propellant. It can be used as reference to the research on firing safety of liquid propellant gun. |
