TAC-TOM式巡航导弹侵彻混凝土数值分析

Numerical Analysis of Tac-Tom Cruise Missile Penetrating Concrete

Tac-Tom式巡航导弹是美国海军最新研制的对地攻击型战术战斧巡航导弹,对现有的防护工程构成了严峻的威胁。为清楚了解其侵彻性能,该文利用有限元计算软件ANSYS/LS-DYNA3D,采用描述弹体遭受大应变、高应变率和高温的约翰逊-库克模型材料本构模型,对该新型导弹以0.7马赫速度侵彻7m厚的混凝土靶板进行了数值模拟,得到的结论证明:该巡航导弹具有很好的穿透力和摧毁硬目标的能力,侵彻混凝土深度达2.92m。此结论的提出对防护高速钻地弹有一定的军事意义。

Tac-Tom Cruise Missile is developed by USA navy for attacking ground targets, and it will threaten the current defense work. In order to make its penetrate performance known clearly, this paper uses the software ANSYS/LS-DYNA3D to simulate the missile penetrating concrete with the velocity of 0.7M and the material mode of Johnson-cook is used for missile. The results prove that the cruise missile has good penetrability and strong power to destroy rigid underground targets, and show some military meaning in resisting high-speed missile.
