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.
In order to analyze the interference mechanism of planar intercalated explosives on the penetrability of rod penetration, the three-dimensional finite element program (LS-DYNA) was used to simulate the penetration process of plane penetration explosive with different penetration angles The results show that the penetrating body penetrates through the interlayer explosives, the end of the penetrating body shows obvious bending phenomenon, and the length of the bent part increases with the incident angle; When the target plate, the crater diameter increases, the penetration path deflection occurs, the ability to penetrate the target plate decreases, the decreasing amplitude increases with the incident angle increases.
