Abstract:In order to study the motion law of projectile penetrating the targets in 1 000~2 000 m/s, high velocity projectile penetration of concrete with different nose shapes was studied respectively. Introduce the study situation of high velocity projectile penetration of concrete, numerical simulation method was used to study, introduce the procedure of numerical simulation, analyze the influence of different nose shapes on high velocity projectile penetration of concrete, the relationship among nose shapes, striking velocity and penetration depth was acquired. The simulation results show that: when the velocity range in 1 400~1 700 m/s, conical head projectile penetration effect is superior to the other projectiles; when the velocity range for more than 1 800 m/s, ogive-conical projectile due to abrasion and deformation has failed at this time, and under the speed range, the penetration effect of the other three projectiles gradually converge. The results of the study have certain reference to the future study of kinetic energy and semi-penetrator projectile.
