长杆弹超高速侵彻金属靶体的实验和模型分析

Experiment and Theoretical Model Analysis of Hypervelocity Penetration of Long-rod Projectiles into Metallic Targets

长杆动能弹体超高速侵彻金属靶板的终点效应是坦克、装甲车和舰船等装备防护设计和穿甲毁伤评估研究的重点。基于已有的大量长杆弹超高速(着靶速度达5.5 km/s)侵彻实验数据,详细讨论了弹体尺寸效应、长径比、弹靶材料和弹体头部形状等参数对长杆弹侵彻深度的影响。进一步结合4组不同弹靶材料的长杆弹侵彻实验数据,对比分析了已有4个长杆弹高速侵彻金属靶体经典理论模型的预测效果,给出了各模型的使用建议。得出的结论可供武器毁伤和金属装甲效能评估和设计参考。

Terminal ballistic effect of long-rod projectile penetrating into metallic target has been a main concern for the damage assessment and protective design of tank,infantry fighting vehicle,warship,etc.The effects of the size,length-to-diameter ratio and nose shape of projectile as well as the projectile and target materials on the depth of penetration( DOP) are discussed based on a large number of penetration data( impact velocity of 5. 5 km/s). The predicted results of the existing four classical theoretical models for long-rod projectiles penetrating into metallic targets are analyzed based on four sets of penetration data with various target and projectile materials. The recommendations on the use of the four theoretical models were given. The conclusions can provide references for the assessment and design of weapons and protective armors.
