选取内弹道敏感因子弹丸启动压力为研究对象,以弹丸启动压力的稳定性为研究目标,以计算机技术和高塑性有限元理论的最新成果为手段,对弹丸的坡膛弹带过程进行了数值仿真研究。实验结果表明,启动压力受坡膛几何角度影响较大,当坡膛角度一定时,弹丸的启动比冲量消耗基本不变。这一结论能够解释长期困扰火炮研究工作者的内弹道峰值问题,在一定程度上证明了研究结果的正确性。

The starting pressure of projectile, as a ballistic sensitive factor, was studied in the paper to improve the stability of the muzzle velocity. The up-to-date computer technology and high plastic finite element theory were applied in the numerical simulation of the band edging properties during the interior ballistic process. The results can explain the problem of peak interior ballistic pressure, which is a long-standing puzzle to artillery researchers. To a certain extent, this also proves the correctness of the findings. The conclusion explains the'mount value'puzzle which has been existing for a long time, this also proves the correction of the study in the paper.
