摘　　要：为了研究不同长径比杆体多速度段与均质装甲靶板毁伤效应关联性,采用AUTODYN软件建立不同工况下的有限元模型,进行了仿真计算,综合分析了弹芯质量4 kg,长径比L/D 10~35,速度段1100~2100 m/s对半无限均质装甲靶板的毁伤破坏情况,得到弹芯不同长径比,多速度段与侵彻深度的关联性数值。In order to study the correlation of multi-velocity section,different length to diameter ratio(L/D ratio)rod body and the damage effect on homogeneous armor targets,a finite element model under different working conditions was established by using AUTODYN software to accomplish the simulation calculation and comprehensive analysis of the damage on semi-infinite homogeneous armor target impacted by a projectile core with a mass of 4 kg,L/D ration of 10 to 35,velocity between 1100 m/s to 2100 m/s,then the correlation value amang the L/D ratio,velocity section and depth of penetration was obtained.The results of this study can provide technical reference for the design and development of rod-type penetrator.
