摘要
介绍了M CA方法的理论基础,并使用该方法对长杆弹侵彻土壤及混凝土复合介质进行二维数值模拟,给出靶板的破坏变形过程,得到了侵彻过程中弹丸速度变化曲线及侵彻深度与着靶速度的关系曲线。数值模拟结果与已有实验现象吻合。
The relative theory of Movable Cellular Automata（MCA） method were introduced in this article, And the 2-D numerical simulations on the penetrations of projectile into soilconcrete targets were completed by this method. The deformation processes of the projectile target are obtained. In addition, the penetration depth vs impact velocity was given. It is demonstrated that the numerical results are well corresponding to experimental observation.
