摘要

摘要: 运用口径36mm的精密成型装药实验，研究了等效厚度相同的碳化硅和氧化铝陶瓷平板装药的防护性能，并与包覆材料为钢的平板装药进行了对比。运用LS-DYNA3D软件，对平板装药与聚能装药的作用过程进行了三维数值模拟。实验结果显示，对于此结构的平板装药，碳化硅和氧化铝陶瓷平板装药使聚能装药侵彻能力分别下降了88%和82%，优于钢板的防护性能。数值模拟结果显示，陶瓷包覆板从边缘至中心依次出现断裂和粉碎现象，钢板与射流后部作用为断续干扰，而陶瓷板为连续干扰。

Abstract: By using the precision shaped charge warheads with the caliber of 36mm, anti-penetration experiments were conducted on the explosive reactive armors(ERAs)encapsulated by three different material layers with the same equivalent thickness, respectively.And the encapsulation layers were made of alumina, silicon carbide and steel plates, respectively.The experimental results show that for this armor configuration, after passing the ERAs with alumina and silicon carbide plates, the penetration depths of the shaped-charge jets decrease 82%and 88%, respectively, which are comparable to those in the cases of steel plates.And the interactions of the jets with the ceramic and steel plates were simulated by applying the finite-element code LS-DYNA3D.The simulation results display that after interaction with the jets, the ceramic plates shatter and break into pieces from the edge to the center.And the interaction mechanism between the shaped-charge jet back and the steel plate is an intermittent disturbance, whereas it is a continuous disturbance with the ceramic plates.
