With AUTODYN-2D code, the formation, flight and penetration processes of sphericity explosively formed projectile (EFP) are simulated. The influence of curvature of liner impose on formation of EFP is studied, and the flight velocity field of EFP is revealed. By analyzing the v-t curve, the attenuation coefficient could be obtained, and then the penetration process of EFP to armor plate are simply analyzed.

应用AUTODYN-2D软件,对准球形爆炸成型弹丸的形成、飞行及侵彻过程进行数值模拟。分析了爆炸成型弹丸的形成过程,药型罩曲率半径对其成型影响;应用拉格朗日/欧拉混合方法对飞行过程进行模拟计算,利用对速度-位移曲线拟合的方法求出衰减系数;并对弹丸侵彻靶板过程作了简要分析。

爆炸成型弹丸  /  侵彻  /  数值模拟

With AUTODYN-2D code, the formation, flight and penetration processes of sphericity explosively formed projectile (EFP) are simulated. The influence of curvature of liner impose on formation of EFP is studied, and the flight velocity field of EFP is revealed. By analyzing the v-t curve, the attenuation coefficient could be obtained, and then the penetration process of EFP to armor plate are simply analyzed.
