弹丸侵彻双层不同材质靶板的数值模拟

为加强装甲目标的防护能力及提高靶板的抗侵彻性能，对弹丸侵彻双层不同材质靶板进行数值模拟。建 立弹丸侵彻靶板的几何和仿真模型，采用ANSYS/LS-DYNA 软件，比较了3 种不同材料靶板的抗侵彻能力，对不 同材质的双层有、无间隔靶板组合的抗侵彻性能进行数值模拟，并对比了靶板排列顺序不同对靶板组合抗侵彻性能 的影响。模拟结果表明：双层不同材质的靶板组合的抗侵彻能力与两层靶板的材质和排列方式有关，双层间隔靶板 组合比双层无间隔靶板组合的抗侵彻性能更好。

Numerical Simulation of Projectile Penetrating into Double-layer Targets of Different Materials

In order to enhance the protection ability of the armor target and improve the anti-penetration performance of the target board, the projectile is penetrating into the double-layer different material target panels for numerical simulation. The geometry and simulation model of the projectile penetrating the target plate were established. The ANSYS/LS-DYNA software was used to compare the anti-penetration ability of the three different material targets, and the anti-invasion of the double-layer target with or without spacing of different materials. The performance was numerically simulated, and the influence of different target arrangement order on the anti-penetration performance of the target combination was compared. The simulation results show that the anti-penetration ability of the two-layer target plate combination is related to the material and arrangement of the two-layer target plate.
