Article Preview

Abstract:

In order to study the influence of projectile structure on the trajectory stability of oblique penetration concrete, this paper designs five kinds of projectile structure including cylinder, stern, tapered tail, cone with 4° and 7°, using LS-DYNA simulation software, the process of five kinds of projectile structure penetration into concrete is studied. Through the analysis of projectile axial resistance, projectile lateral displacement, deflection angle of penetration process and trajectory, it is obtained that the terminal trajectory stability of different projectile structures, from optimal to worse, they are tapered tail, cone, stern and cylinder. It also obtains the projectile lateral displacement and deflection angle of penetration process gradually increase with the increase of oblique angle.
