为了研究靶板侧向运动对弹丸正侵彻效应的影响,运用ANSYS/LS-DYNA模拟在不同攻角条件下弹丸对不同运动速度靶板的正侵彻效应。计算结果表明:无攻角条件下,当靶板侧向运动时,弹丸的剩余速度小于侵彻静止靶板时的剩余速度,有攻角时则相反;靶板运动速度对弹丸侵彻姿态影响比较明显,且弹轴与初始位置的最大偏转角随弹靶X方向的速度之差的增加而增加。本研究揭示了侵彻运动靶过程中弹丸侵彻姿态、速度等的变化规律,可为打击运动目标的有关弹药设计提供参考。
In order to study the effect of the target lateral movement on projectile penetration, ANSYS / LS-DYNA was used to simulate the propelling effect of projectile on different target velocity. The calculated results show that the residual velocity of the projectile is smaller than that of the stationary target when the target moves laterally without the angle of attack, while the attack angle is the opposite. The influence of the target velocity on the projectile penetrating attitude It is obvious that the maximum deflection angle between the elastic axis and the initial position increases with the difference between the velocities in the X direction of the projectile. This study reveals the changing rules of projectile penetrating attitude, velocity and so on during penetration of a moving target, which can provide a reference for the design of ammunition to combat moving targets.
