摘　　要：采用商业有限元软件ABAQUS/Explicit对分层金属靶板在两种形式弹丸冲击下的弹道极限进行了数值研究。讨论了靶板层数和厚度比对弹道极限的影响。通过对比弹丸冲击靶板后的剩余速度,得到了抗侵彻性能的最优构型。结果表明,分层金属靶板在平头弹冲击下具有更优越的弹道性能。低速冲击时,弹丸剩余速度的差异更为显著。此外,随着冲击速度的增大,半球头弹和平头弹的剩余速度差异也逐渐增大。The ballistic resistance of multi-layered metallic targets(LMT)under impact of two types of projectiles was investigated numerically by commercial FEM software ABAQUS/Explict in this paper.The effects of layering number and thickness ratio of the targets on the ballistic resistance were discussed.The optimal configuration of LMT is obtained by studying the residual velocities of projectiles on two types of targets.LMT has the superior ballistic performance against the bluntnosed projectile.The difference on residual velocities of projectiles is more significant when lower velocity impact.Additionally.as the impact velocity increases,the difference of residual velocity between hemispherical-nosed projectile and bluntnosedprojectileincreases.
