摘要

摘要: 利用LS-DYNA软件，对SiC颗粒增强铝合金复合材料的增强相体积百分含量沿厚度连续分布的梯度装甲板进行了抗侵彻过程的数值分析。给出了四种SiC体积含量连续分布的梯度板模型抗侵彻过程的数值计算结果，并与钢板材料进行比较。结果表明：改变梯度装甲板增强颗粒的体积含量沿装甲板厚度方向的分布，能极大地提高梯度装甲板的抗弹击性能，大大地降低防护装甲的自身重量。当SiC颗粒平均体积含量一定时，SiC增强颗粒在表面的体积含量越高，抗侵彻性能越好，也就是f0=0.80，参数b＝4时，具有最佳的抗侵彻能力,比同厚度的钢板要好得多。

Abstract: The numerical simulation of penetration of a functionally graded armour made from Aluminum alloy reinforced by SiC particle was performed. The SiC particle volume fraction varies continuously along the armour thickness followed a power law. The four different armours with the same SiC particle volume fraction, but differen distribution were investigated and compared with steel armour. The results show: The change of the distribution of SiC particle volume fraction along the armour thickness can increase the ability to resist a penetrator. While the SiC particle volume fraction is constant, the higher the SiC particle volume fraction in the surface is, the better the ability of the functionally graded armour against penetration is.The armour with f0=0.8, b=4 show the best anti-penatrator ability among all the cases and it is even better than steel armour.
