弹体侵彻贯穿混凝土与钢筋混凝土等效关系数值分析

Simulation on the Equivalent Relation of Perforating Through Reinforced Concrete and Concrete Target

为了建立钢筋混凝土靶与混凝土靶抗侵彻能力的等效关系,将钢筋混凝土靶与混凝土靶的厚度比值作为钢筋混凝土与混凝土材质的等效因子,利用ANSYS LS-DYNA模拟了当贯穿后的弹体速度相同时,具有相同属性的弹体以相同的入射速度垂直侵彻和贯穿混凝土靶和钢筋混凝土靶的过程.结果表明,研究所得到的等效因子与入射速度的关系式能够为侵彻弹等效靶标构建提供理论依据及数据参考.

To establish the equivalent of perforating through reinforced concrete and concrete, the material＇s equivalent factor of reinforced concrete and concrete was introduced and it is presented by the thickness ratio between reinforced concrete target and concrete target. Suppose the velocities after penetrating the targets are all the same, simulation on the processes of penetrating vertically through reinforced concrete and concrete targets separately by one projectile was performed based on ANSYS LS-DYNA. The relationship between equivalent factor and entering velocity is obtained. This research provides support in theory and data information for building the equivalent target of penetration projectile.
