反机场弹药斜侵彻多层介质靶的三维数值仿真

3D-NUMERICAL SIMULATION OF ANTI-RUN WAY BOMB PENETRATING MULTILAYER MEDIUM

用AUTODYN 3D动力学软件对动能弹斜侵彻混凝土等多层介质靶问题作数值仿真研究 .对某反机场子弹药以不同速度、不同入射角条件 ,斜侵彻机场跑道多层介质靶进行了模拟计算 ,计算结果如侵彻深度、侵彻过载、跳弹情况等符合一般规律 ,对子弹药着速和入射角的控制、弹体结构设计、装药设计、引信设计等方面提供设计参考 .

The numerical simulation of kinetic bomb pe netrating multiplayer medium consisting concrete, cobble and soil in the hydro- code AUTODYN-3D TM is presented. Several different penetrating speed and o blique angle cases are carried out for one anti-runway bomb penetrating process . The simulation results that consist of penetration deep, penetration accelerat ion and rebounding shot situation are accord with common occasion. And they coul d provide design reference for control choice to penetrating speed and oblique a ngle, intensity design of bomb structure, charge intensity design and fuze desig n.
