基于LS-DYNA球形破片穿甲的网格划分研究

The Research on the Mesh Division of the Spherical-debris Penetrating Steel Target Based on LS-DYNA

为了系统地掌握球形破片终点弹道性能,利用LS-DYNA软件进行了球形破片侵彻靶板的有限元分析研究,将实验结果中网格划分的不同情况图形化处理后进行了比较,确定出了网格划分的标准,并通过仿真计算得出了球形破片穿甲后的剩余速度及穿后角度,为装甲目标易损性分析方法的确定和模型计算提供了有益的理论基础。

In order to master the capability of terminal ballistic trajectory of spherical-debris, finite element analysis of spherical-debris penetrating steel target are made by means of LS-DYNA under different mesh, from which the terminal velocity and penetrated angle of spherical-debris are obtained, and the criterion of meshing is defined by analyzing the different situations by graphics, which provides the basic theory for armored vehicle vulnerability analysis and model calculation.
