【摘要】 长管体侵彻靶板的研究具有重要意义。文中结合长管体斜侵彻有限厚靶板的试验,利用三维非线性动力学有限元程序LS-DYNA3D,建立了大倾角下长管体斜侵彻有限厚靶板的有限元分析模型,描述了侵彻全过程的物理和力学现象,并与试验进行了对比,数值结果与试验结果吻合较好,对进一步研究伸出式侵彻体的侵彻能力有一定的参考价值。更多还原

【Abstract】 It is significant to study the penetration of long tube against target. Using the code of LS-DYNA3D,finite element simulation of long tube against 60° obliquity RHA had been performed on the basis of experiments. The main penetrating patterns were obtained and discussed. The results of simulation were in good agreement with experimental results. It would give useful insight into the investigations of extended projectile.更多还原
