摘　　要：TC4-Al_(3)Ti叠层复合材料由于其低密度、高强度的特点被广泛应用于装甲防护材料。为深入研究TC4-Al_(3)Ti叠层复合板的抗侵彻性能,结合弹道冲击试验和有限元数值模拟技术,采用一级轻气炮试验台对TC4-Al_(3)Ti叠层复合板进行弹道冲击试验,并利用LS-DYNA软件建立了接近弹道冲击试验工况的有限元模型,通过对比分析模拟仿真及试验获得的弹体剩余速度和靶板破坏形态,验证了该有限元模型的有效性。在此基础上,重点开展了弹头形状对靶板抗侵彻性能的影响研究。结果表明:在所研究速度范围内,TC4-Al_(3)Ti叠层复合板抗平头弹的侵彻能力最强,其次是半球形头弹,而对球形弹的抵抗能力最弱。Since TC4-Al(3)Ti laminated composite has a low density and a high strength,it is frequently utilized in armor protection materials.Ballistic impact testing of TC4-Al(3)Ti laminated composite boards was conducted using a first-stage light gas gun test bench in order to better investigate the penetration resistance of the laminated board.Additionally,LS-DYNA software was utilized to establish a finite ele-ment model that was close to the conditions of the ballistic impact test.Through a comparison of the pro-jectile′s residual velocity and the target plate failure pattern determined by both simulation and experimenta-tion,the efficacy of the finite element model is confirmed.Based on this,the impact of the shape of the warhead on the target plate’s resistance to penetration is examined.The findings indicate that the TC4-Al_(3)Ti laminated composite plate has the best resistance to flathead projectiles in the speed range of this investigation,followed by semi-spherical projectiles,and the lowest resistance to spherical projectiles.
