无控子弹侵彻机场跑道数值仿真

The Numerical Simulation about Penetration Effect of Unguided Ammunition to Airfield Runway

为准确评估无控子弹对机场跑道的毁伤效能,在建立机场跑道和子弹有限元模型的基础上,运用动力学仿真软件ANSYS/LS-DYNA分别对子弹正侵彻、斜侵彻和带攻角侵彻机场跑道三种情况进行了数值计算,并将不同侵彻类型的毁伤效能进行了对比,仿真结果对提高无控子弹对机场跑道的毁伤效果具有一定的指导意义。

For evaluating the damage effect of unguided ammunition to airfield runway exactly, on the basis of building the finite elemere model of airfield runway and ammunition, the dynamics simulation software ANSYS/LS DYNA was applied, three cases of penetrating airfield runway such as vertical penetrating, lean penetrating and with attack angle penetrating were separately computed, and different damage effects were contrasted. The simulation result provides reference for improving damage effect of unguided ammunition to airfield runway penetration.
