In order to analyze the influence of the detonation of the explosive to the penetration capability of the rod penetrator,the penetration process at different impact angle into plate covered by sandwich explosive are simulated by 3D finite element code(LS-DYNA),which are compared with the corresponding cases without explosive in the middle of two plates.
为了分析平面夹层炸药对杆式侵彻体侵彻能力的干扰机理,采用三维有限元程序(LS-DYNA)分别模拟了不同入射角度杆式侵彻体侵彻放有平面夹层炸药的靶板过程,并和无炸药情况进行了对比分析,发现侵彻体穿过夹层炸药后,端部出现明显的弯曲现象,弯曲部分的长度随着入射角度增大而增大;弯曲的彻体侵彻主靶板时,弹坑直径增大,侵彻路径发生偏转,对靶板的侵彻能力减小,减小幅度随着入射角度的增大而增大。

补充资料：侵彻力
侵彻力——亦称贯穿力，弹头钻入或穿透物体的能力。其大小主要决定于弹头质量、弹头活力的大小和物质的性质。通常以侵彻一定物体的深度来表示。
