混凝土靶强度与射孔弹穿孔深度关系的初步研究

On Linear Regression Analysis of the Penetrating Depth and Target's Compressive Strength

通过102型深穿透射孔弹射流侵彻不同强度柱状混凝土靶试验,结合线性回归分析方法研究了射孔弹对柱状混凝土靶穿孔深度与靶体强度之间的关系,拟合得出二者之间的经验公式,经试验验证该公式预测误差在5%之内,为聚能射孔弹的设计提供理论指导,同时也为射孔弹的研制从试验验证型向计算研究型改进提供了基础数据和研究方法。

Experiment is tried on penetrating columnar concrete target of different strengths with 102 deep penetration perforating charges. The linear regression analysis method is used to study the relation between the penetrating depth of the chargrs and target＇s compression strength, from which the formula between the two is derived. The experiment shows that the error be-tween the formula and the experiment result is less than 5%. The result provides theoretical in-struction for the design of perforating charge. And it could also provide basic data and study methods for the development of perforating charge in the process of experimental confirmation to computation research.
