Abstract

In order to investigate ballistic characteristics of a projectile body penetrating concrete target under combined action of angle of attack and angle of impact, the finite element software LS-DYNA is used to numerically simulate the projectile body penetrating concrete target with different angle of attack and angle of impact at 1 000 m/s. The study focuses on influence of the angle of attack and the angle of impact on the axial penetration depth, radial deviation distance and deflection angle of the projectile body, by analyzing forces applied on the projectile body during the penetration process and axial resistance and radial resistance as well as the deflection moment of the projectile body, and gains a rule of their influence on the ballistic characteristics. The conclusions are as follows: with the increase of the impact angle, the influences trend of the angle of attack on the deflection angle of the projectile body is significantly increased. In a certain range, the attack angle whose initial direction is opposite to the impact angle can improve the penetration ability of the missile body, while the attack Angle whose initial direction is the same as the impact angle can weaken the penetration ability. When the impact angle is too large, no matter whether the direction of the initial attack angle is the same with the impact angle or not, the penetration ability will be weakened, and it will be more obvious with increase of the impact angle. The research results can provide some references for the development of ground-penetrating bomb.
