摘要
用移动元胞自动机法(movable cellular automata,MCA)计算了质量和速度相同、长细比不同的杆式穿甲弹对侵彻过程影响的实例,计算结果与实验符合。移动元胞自动机法能较好模拟爆炸和高速穿甲侵彻中材料瞬间的变形、破碎和飞散过程。
The movable cellular automata （MCA） method was improved and applied to simulate the penetration process of tungsten long rod projectiles into 27SiMnMo target plates. At an impact velocity of 1000 m/s, the simulated results show that different aspect ratios correspond to different maximal penetration depths and the maximal penetration depth increases with the increase of the aspect ratio, but the aspect ratios over 25 affect weakly penetration depth under the given experimental conditions. The computed temperature fields for the projectiles and targets are in agreement with the experimental results. The movable cellular automata （MCA） method can be used to effectively analyze the damage process of the projectile-target interaction.
