基于ANSYS/LS-DYNA的钻地战斗部侵彻混凝土靶数值研究

NUMERICAL SIMULATION OF EPW PENETRATING CONCRETE TARGET BY ANSYS/LS-DYNA

采用ANSYS/LS-DYNA软件,对某钻地战斗部侵彻混凝土靶进行数值模拟。模拟了钻地战斗部在给定的初速与起爆时间下侵彻并毁伤混凝土靶板的过程,得出整个钻地战斗部的最薄弱位置在战斗部头部后端的战斗部薄壳体位置处;钻地战斗部完全侵入混凝土靶板后不同的起爆时间对混凝土靶板的毁伤效果差异不大。

The numerical simulations of EPW penetrating concrete target were completed by ANSYS/LS-DYNA. We mainly simulate the process of burrow warheads in given velocity and initiating time chester and mutilate concrete target invasion. The simulation concludes the weakest position of EPW is located at the warhead thin shell in the rear of the warhead head. After EPW completely invades concrete target board, the destructive effect on the target board is so little difference at different initiation time.
