摘　　要：为提高传统特种能源成型干扰器(EFP)侵彻部的侵彻范围和干扰效果,通过对EFP侵彻部进行结构优化,在不影响EFP成型的基础上,将预制破片和EFP侵彻部这2种干扰元进行融合,形成EFP动能干扰复合侵彻部。采用AUTODYN有限元分析软件将动能干扰侵彻部的壳体结构和药型罩外形对破片运动状态和药型罩变形情况的影响进行数值模拟。结果表明,采用球缺形药型罩有利于形成EFP;当壳体与水平角度在-8°~-10°范围内,预制破片和形成的EFP速度最大,可增大侵彻部的干扰效果。In order to improve the penetration range and jamming effect of the traditional EFP penetration part,the structure of the EFP penetration part is optimized.On the basis of not affecting the forming of EFP,the two interference elements of the prefabricated fragment and the EFP penetration part are integrated to form the EFP kinetic energy interference composite penetration part.The effects of the shell structure of the kinetic energy interference penetration and the shape of the liner on the fragment motion and the cover deformation are numerically simulated using AUTODYN finite element analysis software.The results show that the spherical shaped liner is beneficial to the formation of EFP;when the angle between the shell and the horizontal is in the range of-8°~-10°,the velocity of prefabricated fragments and EFP is the highest,which can increase the interference effect of the penetration part.
