摘要
以舰船结构为目标,运用ANSYS/LS-DYNA,用截卵形弹丸对均质靶板和加筋靶板侵彻进行数值模拟研究,分析靶板的破坏情况、弹丸的剩余速度、弹丸的变形情况以及弹道的偏转,结果表明数值模拟是可行的,并建立卵形弹丸模型采用上述的J-C模型对与上述同样的均质靶板和加筋靶板进行穿甲进行数值模拟,研究靶板的破坏情况、弹丸的剩余速度、弹丸变形以及弹道偏转情况,并运用理论计算公式计算弹丸的剩余速度与之相比较,证明卵形弹丸的数值模拟是正确的。
According to the structure of warships,with the ANSYS / LS-DYNA,the numerical simulation was performed with the truncated oval-nosed projectiles against homogeneous and stiffened plates penetration to analyze the target damage,the residual velocities of projectiles,the deformation of projectiles and deflection of trajectory. Good agreement was obtained between the numerical simulations and experimental results. And the oval-nosed projectiles were established. Numerical simulations were performed with the oval-nosed projectiles against the same plates to analyze target damage,residual velocities of projectiles,deformation and deflection of ballistic trajectory. Good agreement was obtained between the numerical simulations and theoretical results.
