动能弹斜侵彻运动装甲目标的数值模拟

利用LS-DYNA3D软件对弹体侵彻运动装甲板进行了数值模拟研究,从弹体剩余速度和靶板破坏程度的角度分析了弹体侵彻运动装甲的能力.得出了弹体速度随时间的变化规律,结果表明,弹体初速度、装甲运动速度及方向、装甲的倾角对弹体的侵彻能力都有很大的影响.

Numerical Simulation of Oblique Penetration of KE Projectile Penetrating Moving Armored Plate

The process of penetrating obliquely moving armored plate with KE projectile was numerically simulated by the finite element code LS-DYNA.The damage images of the moving armored targets are described and the variation of remaining velocity to time was obtained for KE projectile.The simulation results indicate that impact velocity、impact angle、moving armored plate speed and direction had effects on the ability of KE projectile penetrating moving armored targets.
