AUTODYN反机场跑道破甲战斗部结构设计
本文首先对聚能装药进行结构设计，包括炸药的选择、装药形状和尺寸的确定、隔板设计、药型罩形状、材料、锥角、壁厚的确定以及炸高的选择等。
其次对机场跑道目标特性进行分析，理论分析研究聚能射流的形成及侵彻不同厚度的多层复合介质，利用工程算法计算聚能装药对机场跑道的侵彻。
最后利用AUTODYN仿真软件对聚能射流的形成及侵彻机场跑道靶板进行数值仿真，分析侵彻深度及侵彻孔径，因工程算法的误差比较大，所以计算结果与实际有出入，需要对成型装药进行重新优化设计，然后继续进行数值仿真，直到达到设计指标要求。25475

Title the design of anti-runway armor penetration Warhead
Abstract
The air force is an important influencing factor to the war.Destroy enemy’s airport runway efficiently can hinder the plane from taking off,paralyze enemy’s air force completely,gain the initiative in a war.The anti-runway weapon becomes an important direction of research in the world.The design of anti-runway armor penetration warhead has important significance for the war in the future.
First,this thesis design the structure of shaped charge,including the choice of explosive,the shape and size of explosive,the design of clapboard，the shape of liner,material,angle of cone,wall thickness and the height of burst.
Second,analyze the target characteristics of runway,theoretically analyze the formation of jet flow and the penetration of different thickness of multilayer medium,calculate the penetration of shaped charge to runway with engineering calculation.
At last,using AUTODYN simulation software to simulate the formation of shaped jet and penetration of the airport runway target board,analyze the depth of penetration and diameter of the hole，the error of engineering method is large,so the calculation results and the actual have discrepancy,need to redesign and optimize the shaped charge,silmulate again,until meet the requirements of design index.
Keywords armor penetration warhead，shaped charge，liner,anti-runway，jet，simulation
