摘要
在实验的基础上,运用数值仿真方法研究了长径比约为1∶1钨柱的着靶姿态对40Cr钢板侵彻效应的影响。获得了入射角与极限穿透速度的关系,以及侵彻速度相同时,入射角与穿透靶板后剩余速度的关系。在此基础上研究了同种规格的钨柱侵彻不同厚度的均质装甲钢和40Cr钢板时极限穿透速度的关系,得到了两者速度比为1.13∶1的结论,为寻求低成本等效靶板提供了有效试验依据。这些研究成果对破片毁伤战斗部的设计具有实际指导意义。
On the basis of experimental research, penetration effect of the targeting attitude of tungsten column whose length-diameter ratio is 1:1 target on 40Cr target was studied by numerical simulation. The relationship between incident angle and the limit penetration veloci- ty, and the relationship between the incident angle and residual velocity after penetrating target were got. At the same time, limit penetra- tion velocity of tungsten penetrator with the same specifications but different thickness between homogeneous armor steel and 40Cr steel was studied. The conclusion is that two speed ratio is 1.13: 1, providing the basis for seeking the low equivalent target. The results have actual guiding significance on fragment damaging warhead.
