摘　　要：飞矛作为一种空间碎片清理方式已有许多相关研究,但目前飞矛对目标的附着大多依靠目标对飞矛的挤压摩擦,为能够使飞矛更好地附着到目标上,该研究设计一种光滑型飞矛和一种倒刺型飞矛并对铝蜂窝板进行冲击试验,分析对比飞矛侧面有无倒刺2种情况下对侵彻速度、嵌入深度等的影响。根据试验结果修正仿真模型,并利用仿真继续进行分析。最终结果表明,倒刺型结构的飞矛能够附着到目标上;另外在使用相同速度对铝蜂窝板侵彻时,倒刺型飞矛的嵌入深度先是小于光滑型飞矛,而后又大于光滑型飞矛,并且弹道极限低于光滑型飞矛。Flying spear as a way to clean up space debris has been studied a lot,but at present,the attachment of flying spear to the target mostly depends on the extrusion and friction between the target and flying spear,in order to make the flying spear adhere to the target better,in this study,a smooth flying spear and an inverted flying spear were designed,and the impact test on aluminum honeycomb plate was carried out.This paper analyzes and compares the influence on the penetration speed and embedding depth with or without inverted thorns on the side of the spear.The simulation model is modified according to the test results,and the simulation is used to continue the analysis.The final results show that the flying spear of the barbed structure can be attached to the target,and when penetrating the aluminum honeycomb plate at the same speed,the embedding depth of the inverted spear is first smaller than that of the smooth spear,and then larger than that of the smooth spear,and the ballistic limit is lower than that of the smooth spear.
