摘　　要：为了研究垫块结构PELE对混凝土靶的侵彻效果,采用数值模拟方法对不同尺寸和斜角的垫块结构PELE侵彻混凝土靶板过程进行数值模拟,对比各方案侵彻靶板后的开孔半径和剩余速度。结果表明,增加垫块结构后,PELE的侵彻效果相对0厚度即没有垫块时明显提高,在着速和垫块长度相同的条件下,垫块斜角越小产生孔径越大,厚度值较大的垫块相对较小的垫块剩余速度大,此结果可为新型PELE的设计提供一定的参考。In order to study the penetration effect of PELE on concrete target,the study conducts numerical simulation method to simulate the penetration process of PELE on concrete target with different sizes and oblique angles,and compares the opening radius and residual velocity of each scheme.The results show that with the addition of pad structure,the penetration effect of PELE is significantly improved compared with 0 thickness,i.e.without pad.Under the condition that the velocity is the same as the length of the pad,the smaller the inclination of the pad is,the larger the aperture is.And the residual velocity of the pad is faster compared with that of the smaller pad.The result can provide certain reference for the design of new PELE.
