摘要
Oblique deep penetration is a common form of projectile penetration into the target. In view of the fact that most of the research work is focused on the trajectory of vertical penetration, the trajectory and law of oblique penetration are discussed in this paper. This paper studies the impact of different initial angles of attack on projectile trajectory and fuze impact in oblique penetration by simulating projectile penetrating target with LS DYNA software. The results show that with the increase of attack angle, the deflection of trajectory is more obvious, the penetration depth is smaller, and the impact acceleration amplitude of fuze is larger. The research content of this paper provides a reference for oblique penetration of concrete target and impact performance of fuze, and is of great significance for the construction and protection of underground fortifications.
