通过对一种带铝风帽弹丸穿透多层薄间隙装甲现象的分析,给出了一种计算弹丸穿透每层薄装甲之后的剩余质量、剩余速度的工程方法。模型将弹丸对薄板的穿透过程分为两个阶段。计算与相应的实验结果符合较好。
Through the analysis of the phenomenon that a kind of aluminum hood cap penetrates the multilayered thin gap armor, an engineering method to calculate the remaining mass and residual velocity after the projectile penetrates each thin armor is given. The model divides the projectile’s penetration into the sheet into two stages. The calculation is in good agreement with the corresponding experimental results.
