Title Research on high speed projectile penetration rule
Abstract
Kinetic energy projectile speed penetration into concrete target is of great significance for military protection engineering, and it is gradually becoming a hotspot in the field of military scientific research problem.In this paper ,focused on kinetic energy projectile penetrating concrete target, using ANSYS AUTODYN simulation software, conducting 3D simulation calculation on the different velocity kinetic energy projectile penetrating into different strength of the reinforced concrete target, taking a research and analysis on high-speed projectile on the penetration of concrete target. In this paper the projectiles velocities in the range of 800m/s～ 1200m/s,by changing the diameter of steel bar and arranged to change the target intensity density.Combined simulation with relative theory and research，some high velocity penetration rule were : the ability of projectile penetration increases as the projectile velocity increases; as the plate material strength increasing,resisting projectile penetration ability increasing.Reinforcement diameter bigger, Steel grid size is smaller, more detailed arrangement. Resisting projectile penetration ability.
Keywords Kinetic energy projectile numerical simulation high velocity penetration reinforced concrete Target strength
