利用MSC/DYTRAN程序仿真分析导弹战斗部立方体破片的侵彻威力

对反辐射导弹的破片杀伤战斗部中较为常见的立方体破片的 3种典型姿态侵彻 (尖端、棱边及正面侵彻 ) 4mm厚 94 5钢的侵彻过程进行仿真数值计算 .通过仿真计算 ,结合实验结果比较 ,得出结论 :不同初始侵彻姿态的立方体破片在侵彻过程中 ,由于旋转角速度的作用及稳定性的要求 ,破片的侵彻姿态将趋于正面侵彻 .不同姿态的侵彻 ,侵彻威力相差不大

The resistance ability of steel plate for penetration by cubic fragment through MSC/Dytran

About the fragment penetration, the processes of the three typical penetrative gesture (tip, angle and face) of the cubic fragment of anti|radiation missile penetrating a 4mm target of steel 945 are simulated and calculated in this paper. With the comparison of experimental outputs the simulating and calculating conclusions are put out: fragments with different initial penetrative gesture have large difference in penetrative power toward the target. But in the penetrative process of cubic fragments with different initial penetrative gesture, the penetrative gesture tends to face penetration, because of the effect of the rotation velocity and stability, different initial penetrative gestures have little difference in penetrative power.
