摘要
针对电磁轨道炮超高速弹丸侵彻靶板问题,建立超高速弹丸与靶板模型,利用Abaqus软件,结合Mie-Grüneisen状态方程、Johnson-Cook本构方程和Johnson-Cook断裂准则,对钨合金弹丸以同样速度不同旋转速度侵彻靶板,对钨合金弹丸以不同速度侵彻同样靶板,对钨合金弹丸以同样速度侵彻不同材料靶板进行仿真研究。对各种条件下超高速弹丸侵彻靶板过程进行了剖析,得到4条仿真结论。
To solve the problem of hypervelocity projectile penetrating into target, models of hypervelocity projectile and target are built. Using Abaqus, Mie-Grüneisen state equation, Johnson-Cook hardening equation and Johnson-Cook failure criterion, simulation studies on penetration into target of tungsten alloy projectile are done, including same velocity but different angular speed and different velocity but same target and same velocity but different material target. Based on simulation results, the procedure of penetration are analyzed, and four conclusions are proposed.
