正撞击下双层墙结构防护屏防护性能仿真研究

Simulation to test bumper shielding effectiveness of double-wall structure under projectile hypervelocity impact

文章利用AUTODYN软件对铝合金球形弹丸正撞击双层墙防护结构进行了仿真研究,比较了双层墙防护结构中铝合金材料和复合材料防护屏的防护性能。结果表明:在相同的面密度和构型下,双层墙防护结构中铝合金防护屏的防护效果优于复合材料防护屏。

Numerical simulation of spherical projectile hypervelocity impact on double-wall shielding structures is carried out using AUTODYN hydro-codes.The shielding performance of aluminum alloy bumpers is compared with that of the composite material bumpers.The results show that the shielding effectiveness of the former is better than that of the latter in a double-wall shielding structures under the condition of identical area density and configuration.
