为了使钻地弹的侵彻深度达到毁伤的目的
通过在弹体表面刻螺旋槽
基于TrueGrid建立了三种不同结构的弹丸有限元模型.应用LS-DYNA3D进行了数值模拟仿真
初步探讨了三种不同结构的弹丸和混凝土相互作用的规律
得到了作用过程中三种不同结构弹丸的破坏效能.结果表明:由于外表面刻螺旋槽
弹丸在侵彻过程中产生旋转力矩剪切混凝土
使侵彻效能提高了20%.研究结果可为钻地弹在增加侵彻深度效能上提供借鉴.
In order to achieve damage efficiency of rotated earth penetrating projectile
spiral groove was shaped on the surface of projectile.Numerical simulations were carried out through Ls-DYNA3D and finite element model created by TrueGrid
and the interaction laws of the three kinds of projectiles and concrete target were preliminarily discussed
meanwhile
the damage efficiency of the three kinds of projectiles was obtained.The penetrating performance of the projectile with spiral groove improves by 20% because of the running torque produced by the spiral groove.The result of the research can provide a reference for increasing penetrating depth of earth penetrating projectile.
