摘　　要：为研究675装甲钢遮弹层的防护能力和抗巡航导弹侵彻性能,分析侵彻过程中弹靶作用机理以及装甲钢力学行为,设计了缩比巡航导弹侵彻675装甲钢的实验及相应的数值模拟。结果表明:675装甲钢硬度很高,侵彻基本保持在开坑阶段,弹坑面积小,靶板整体变形并不显著;侵彻过程中弹丸由弹头与弹身交接处断裂,因弹头侵蚀和弹丸断裂损失的能量较大,致使靶板变形小,靶板变形主要发生在弹丸断裂前;随着侵彻速度由350 m/s增至600 m/s,靶板弹坑深度和背突高度随速度线性增加;弹坑直径由1.1倍弹丸外径增至1.5倍弹丸外径,弹丸因质量侵蚀损失的能量由总能量的42.4%增加至68.6%;弹丸加速度在靶板磨损弹头部一半,弹头与弹身交接处发生塑性变形时达到最大。In order to study the penetration resistance of 675 armor steel shield against cruise missile and analyze the mechanism of projectile and target action and mechanical behavior of armor steel,the experiments and numerical simulations of scaled cruise missile penetration of 675 armor steel are carried out.On this basis,the numerical simulation of 675 armor steel at different projectile penetration velocities are carried out.The results show that the scaled cruise missile penetrates into 675 armor steel,and because of the high hardness of the armor steel,the penetration is basically kept in the cratering stage,the cratering area and depth are small,and the overall deformation of the target plate is not significant.The projectile is fractured at the junction between the warhead and the projectile body.Because of the erosion of the projectile head and the loss of the energy of the projectile fracture,the deformation of the target plate mainly occurs before the fracture of the projectile.As the penetration velocity increases from 350 m/s to 600 m/s,the deformations of the target plate increase linearly with the velocity.The crater diameter increases from 1.1 times the outer diameter of the projectile to 1.5 times the outer diameter of the projectile,and the energy loss causes by mass erosion increases from 42.4%to 68.6%.The acceleration of the projectile reaches the maximum when the plastic deformation begins at the transition region from head to body of projectile,and then decreases rapidly until the projectile fractures.When the residual projectile begins to penetrate the target,the acceleration increases,then enters a plateau period where it oscillates and decreases slightly,and finally decreases to 0 rapidly.The acceleration of the projectile reaches the maximum when the plastic deformation begins at the transition region from head to body of projectile.
