摘　　要：根据可膨胀石墨燃爆过程需要,采用数值方法对可膨胀石墨燃爆过程中装药壳体对压力的影响规律进行了仿真研究。仿真结果表明,当装药壳体较厚时,内部高压的持续时间较长,能够为可膨胀石墨提供一个较长时间的受热环境,有利于可膨胀石墨充分膨化。因此,在保证装药压力能够可靠破碎壳体的前提下,在弹药壳体设计过程中,应尽量选用较厚的壳体。According to the deflagration requirement of expandable graphite, this article uses numerical method to conduct simulation study of the influence of ammunition charging shell on the pressure in the deflagration process of expandable graphite. The simulation results show that when the ammunition charging shell is thick, the duration of the internal pressure is long, so it can provide heated environment expandable graphite for a long time and is conducive to the full expansion of expandable graphite. Therefore, in the ammunition shell design process, a thicker shell should be used.
