摘要

为研究具有多层嵌套形式的复合结构PELE的轴向剩余速度计算方法,通过对侵彻过程和冲击波传播过程的分析,结合能量守恒定律、一维平面冲击波理论等,得到了轴向剩余速度的理论计算方法;对在不同速度下使用不同弹芯组合的弹丸进行数值模拟,得到了相同计算条件下的数值模拟与理论计算的剩余速度,并针对文献中的实验进行验证。结果表明:理论计算结果与数值模拟结果以及文献实验结果吻合度较好,可用于计算复合结构PELE轴向剩余速度。

Abstract

In order to study the calculation method of axial residual velocity of PELE with multi-layer nested structure, the theoretical calculation method of axial residual velocity is obtained by analyzing penetration process and shock wave propagation process, combining energy conservation law and one-dimensional plane shock wave theory, etc. The projectiles with different core combinations at different speeds are numerically simulated and the phase is obtained.The residual velocities of numerical simulation and theoretical calculation under the same calculation conditions are verified by experiments in literatures.The results show that the theoretical calculation results are in good agreement with the numerical simulation results and the experimental results in literature. It can be used to calculate the axial residual velocity of PELE for composite structures.

Key words： PELE; residual velocity; numerical simulation; penetration process
