| 摘 要： | 文章用LS-DYNA3D软件对155mm榴弹侵彻块石遮弹层（尺寸分别为：20cm、40 cm、60 cm）进行了数值模拟,分析了不同尺寸下的侵彻效果、弹体速度时程曲线、位移时程曲线,描述了边界效应对侵彻深度的影响,得出了块石尺寸和弹径的比值对弹坑直径、侵彻深度影响较大的结论。

| Abstract: | The 155-mm-diameter howitzer penetrated rock shelter layer was numerically simulated by using LS-DYNA3D(the dimensions were 20cm,40cm and 60cm).The penetrated effect and the velocity and displacement-time history curves of the howitzer were analyzed.The simulation explained how the rock boundary affected penetrated depth and the rate rock dimension to howitzer diameter had much effect on crater diameter and penetrated depth,which could be good reference for related researchers. |
