摘要
为了给装备的改进设计和战斗损伤分析提供依据,利用LS-DYNA进行了球形破片侵彻靶板的有限元分析,在确定钨球破片和LY-12铝合金靶扳的材料模型并进行计算验证的基础上,利用不同尺寸的球形破片对不同厚度的靶板进行了仿真分析,得出了不同情况下破片对靶板的撞击相图,并对靶板的损伤模式进行了分析。
In order to provide data foundation both for equipment improvement and for battle damage analysis,finite ele- ment analysis of spherical fragment penetrating target by LS-DYNA is made in this paper.Based on determination of the material models of tungsten spherical fragment and LY-12 aluminum alloy and validation of the models,simulation analysis of different spherical fragments penetrating different LY-12 targets are made.from which the charts of frag- ments penetrating targets under different cases are obtained,and the damage modes of targets are analyzed.
