| 摘 要： | 运用Ls-dyna软件对弹体侵彻单块岩石和块石遮弹层进行数值模拟。结果表明:块石层对弹体侵彻具有很好的防护效果,块石破碎产生强烈的局部应力使弹体产生偏转从而减小侵彻的深度;块石必须有一定的尺寸大小和强度与弹体相匹配,设计良好并且有一定厚度的块石层能有效地阻止弹体侵彻。

| Abstract: | Rock anti-penetration layers against penetrating were investigated by using the commercial FEM software,LS-DYNA.The numerical results show that rock layers can make efficient protective results because of additional local stress caused by rock breaking,and can decrease penetration depth of projectile.If rock anti-penetration layers are designed by specific methods that dimension and strength of rock are in proportion to the projectile,rock layers can effectively resist penetration by projectile. |
