摘　　要：利用显示动力学有限元程序ANSYS/LS-DYNA模拟着靶速度为2.0Ma和2.5Ma的战斗部对多层间隔靶板侵彻的过程。结果表明：钛合金抗弹性能良好可作为战斗部的壳体材料;战斗部壳体结构强度满足侵彻需求。The warhead was launched at impact velocity of 2.0Ma and 2.SMa. It impacted a 4-layer space armor steel at 0°. The process of the penetration was simulated with explicit finite element software ANSYS/LS- DYNA. The conclusion and its analysis indicated that TC4 performed well in penetrating and it could be made into the shell of missile warhead, and the warhead shell structure strength was strong enough to satisfy the need of penetration.
