摘　　要：分析了ANSYS/LS-DYNA常用的两种数值计算方法,Lagrange算法和ALE算法。给出了预测钢板门在大速度破片侵彻与贯穿时的计算公式,对破片侵彻双层钢板门过程进行数值模拟,结果较为一致。数值模拟是对经验公式和试验研究的有益补充。In this paper,the two numerical arithmetic Lagrange and Arbitrary Lagrange-Eulerian in ANSYS/LS-DYNA were analyzed.The formula used in penetration and perforation of double-steel door by fragment with high speed was given,and the process was simulated.The results of simulation were in good agreement.Numerical simulation is helpful supplement for empirical formula and test research.
