利用LS-DYNA3D有限元软件对钨合金长杆弹斜侵彻运动靶板进行了数值模拟研究,从长杆弹剩余速度和靶板破坏程度的角度分析了动能弹体斜侵彻横向运动靶板的能力。从中得出了弹体的变化规律和靶板的物理图像,结果表明:长杆弹初速度及长细比、靶板运动方向及速度、靶板的倾角对弹体的侵彻能力都有很大的影响。

By the finite element code LS-DYNA3D, the process of obliquely penetrating moving targets with the tungsten alloy long-rod projectile was numerically simulated. The analysis on the capacity of KE projectile penetrating obliquely moving targets was based on the residual velocity of long-rod projectile and the damage degree of the moving targets. The physical figures of targets and variation curves of projectile were obtained in the case of penetration. The simulation results show that initial velocity and slenderness ratio of long-rod projectile, speed and direction of moving targets, impact angle had great effect on the ability of long-rod projectile penetrating moving targets.
