摘　　要：为提升复合装甲抗弹性能,用Autodyn软件建立二维模型,通过SPH算法对单一UHMWPE纤维复合材料靶板进行数值模拟,研究其侵彻机理和破坏模式,对B4C陶瓷/UHMWPE复合材料靶板的5种结构进行侵彻性能仿真预测,并验证模拟结果。结果表明:迎弹面应选刚度和硬度高的材料,当用B4C陶瓷时,B4C陶瓷与UHMWPE复合材料靶板厚度比为4∶10,抗弹性能最佳。试验结果与模拟结果一致性较好。In order to improve the ballistic performance of the composite armor,Autodyn software was used to establish a twodimensional model,and a single UHMWPE fiber composite target was numerically simulated through the SPH algorithm to study its penetration mechanism and failure mode. Furthermore,the penetration performance simulation prediction of the five structural forms of the B4 C ceramic/UHMWPE material composite structure target plate was carried out,and the results were verified by experiments and simulations. The results show that the material with high rigidity and hardness should be selected for the projectile facing surface. When B4 C ceramic is used on the front surface,the thickness ratio of B4 C ceramic and UHMWPE composite target plate is 4∶10,and the ballistic performance is the best. The test results are in good agreement with the simulation results.
