对10号钢和紫铜材料EFP侵彻对50 mm厚603均质装甲靶板的性能进行了研究.应用ANSYS/LS-DYNA软件对两种EFP的成型和侵彻靶板过程进行了数值模拟,分析了两种EFP侵彻性能差异存在的内在原因.结果表明,10号钢EFP的穿深能力小于紫铜EFP,而扩孔能力较为显著,其靶板入口尺寸约为紫铜EFP的1.5倍.认为侵彻性能的差别由材料特性、EFP形状和速度分布引起,而靶板入口大小由尾翼大小决定.

The test on the penetration performance of the 10# steel and copper EFP to the 603 RHA was carried out. In order to analyze the internal causes what make the differences of penetration performance between the 10# steel EFP and copper EFP, the forming and penetration process of two kinds of EFP were simulated by ANSYS/LS-DYNA. The results show that the penetration ability of 10# steel EFP is worse than the copper EFP,but the reaming ability is much better, the entrance aperture is about 1.5 times to the copper EFP. Considering that the differences in penetration performance are caused by the material performance of liner, the shape of EFP and the velocity distribution,whereas the differences in entrance dimension of target are determined by the fin dimension.
