| 摘 要： | PELE(横向效应增强型侵彻体)撞击靶板能够产生明显的横向效应，横向效应的强弱受多种因素的影响。通过改变PELE的外壳材料、弹芯材料及着靶速度，对PELE垂直侵彻薄靶进行了实验研究。基于实验结果，对PELE侵彻靶板的过程进行了受力分析，阐明了横向效应产生的机理，建立了破片轴向剩余速度和径向速度的理论模型，模型计算结果与实验结果吻合较好。理论分析和实验结果表明，外壳材料的压拉强度比、弹芯材料的泊松比和弹性模量以及着靶速度等对PELE横向效应影响显著。本研究对PELE的设计和改进有一定的参考价值。

| Abstract: | By changing the jacket,the filler and the impact velocity of the PELE projectiles,the impact behaviors of the PELE projectiles perpendicularly perforating thin target plates were investigated experimentally.On the basis of the experimental results,the stresses of the PELE projectiles during their penetration into the targets were analyzed and the lateral effect production mechanism was illuminated.On some hypotheses,the theoretic models were established for the residual and radial velocities of PELE project... |
