| 摘 要： | 应用ANSYS/LS-DYNA的聚能装药侵彻仿真时,药型罩材料模型的选择有多种,对仿真结果之间的差别进行了比较。在炸药、药型罩结构等条件相同的情况下,选择Johnson-Cook与Steinberg两种材料模型,利用ANSYS/LS-DYNA软件对聚能射流侵彻靶板进行仿真。对比仿真结果,得出两种模型都能很好地模拟射流的形成及侵彻过程,且各时刻射流头部最高速度差值很小。

| Abstract: | When carry out simulation of shaped charge penetration that based on ANSYS/LS-DYNA,many kinds of material model of the liner can be used,the difference between them is compared.Two kinds of material model were introduced,based on the same condition,such as explosive,liner structure,Johnson-Cook and Steinberg model were selected for liner.The process of shaped charge jet penetration into target was simulated using ANSYS/LS-DYNA,the results compared and showed that these two kinds of model can simulate the fo... |
