碳化硅-铝射流侵彻新型反应装甲的仿真研究
|
摘要
为研究碳化硅-铝(SiC-Al)射流对新型反应装甲的侵彻性能,运用AUTODYN软件仿真计算,分析不同参数的SiC-Al射流成型规律以及对新型反应装甲的侵彻效果。结果表明:锥角、装药高度对SiC-Al射流成型影响较大,锥角80°时成型效果最好,装药高度为1.3D和1.5D时射流头部较稳定;射流头部速度随锥角、壁厚的增大而减小,随装药高度的增大而增大;射流侵彻反应装甲时,侵彻效果随药型罩壁厚的增大而增强,随炸高的减小而减弱,可实现对新型反应装甲的穿而不爆。
In order to study the penetrating performance of silicon carbide-aluminum(SiC-Al) jet for new reactive armor,AUTODYN software was used to simulate and calculate,the formation rules of SiC-Al jet with different parameters and the penetration effect on the new reactive armor were analyzed. The results show that the cone angle and charge height have great influence on the forming of SiC-Al jet,the forming effect is the best when the cone angle is 80 degrees,the jet head is more stable when the charging height is 1.3D and 1.5D. The velocity of jet head decreases with the increase of the cone angle and wall thickness,and increases with the increase of the charge height. When the jet penetrates into the reaction armor,the penetration effect increases with the increase of wall thickness and decreases with the decrease of explosion height,and the new reactive armor can be penetrated without explosion.
