For improving projectile ballistic stability under oblique penetration to multi-layer target,design the multi-layer composite structure warhead.Use ansys/ls-dyna to carry out numerical simulation for composite structure warhead oblique penetration to multi-layer target,and analyze the influence of warhead structure with different material combinations on projectile residual kinetic energy and ballistic stability.The results show that,under 20° striking angle,the multi-layer structure warhead has grinding function.The ballistic stability and quality consumption of two-layer and three-layer warhead are better than standard projectile.The optimal scheme of designed multi-layer structure warhead is two-layer alloy steel structure warhead.The can provide a reference and basis for the design of the warrior warhead and the oblique penetration trajectory analysis of the small-caliber bullet and the multi-layer target.
