603靶板抗EFP侵彻等效靶实验研究

Experimental Study on the Equivalent Target of 603 Armor Penetrated by EFP

在EFP对有限厚45#碳钢靶和有限厚603靶板侵彻的脉冲X光摄影试验及靶后破片回收试验的基础上,分析了EFP对有限厚45#碳钢靶和有限厚603靶板的侵彻规律,进而通过对试验结果的数据处理,获得了EFP对有限厚45#碳钢靶和有限厚603靶板的极限穿透速度。利用极限穿透速度相等条件,获得了45#碳钢板与603靶板的等效关系。

On the basis of the experiments of pusle X-ray photograph and recovering fragment behind the target, the damage phenomena of 45# steel plate and 603 armor with limited thickness while penetrated by EFP is studied. In the meantime, the penetration law is analyzed. An empirical formula on the limited penetration velocity of EFP is established. The equivalent relations of 45# steel plate and 603 armor are obtained through the equally limit penetration velocity.
