摘要： 为研究高强材料与异形结构联合防护下工程的抗侵彻能力，设计了一种超高强球面结构加固靶体，利用
∅ 125 mm 火炮开展了系列 400 m/s 冲击速度下的侵彻试验，得到了弹体破坏形态和靶体侵彻深度等试验数据。结合半
无限厚混凝土靶体的抗侵彻试验进行对比分析，探讨了材料高强力学性能以及球状偏航结构等因素对弹体偏转破碎、
侵彻能力的影响。结果表明：在 400 m/s 的侵彻速度下，设计的超高强球面结构的无量纲侵彻深度为 0.11，弹体偏转角
为 83°，质量损失率达 23.66%，结构抗侵彻能力为 C40 混凝土的 9 倍，防护能力较普通混凝土有显著提升。超高强球面
结构的非对称撞击力促使来袭弹发生偏转破碎，使弹体头部产生严重侵蚀，并在侵彻过程中产生跳弹、二次着靶以及
折断等行为，可有效阻挡弹体侵入结构内部，极大削弱来袭弹体在防护结构中的侵爆作用。

Abstract: To explore the anti-penetration abilities of irregular structures made of high-strength alloy steel, a target enhanced
with ultra-high-strength spherical structures (UHS-SS) was manufactured in this work. The UHS-SS is fabricated from ultra-
high-strength steel (UHSS) and mechanically anchored to the target via threaded high-tensile rods, ensuring structural integrity
under projectile penetration loading. A series of penetration tests at an impact velocity of 400 m/s was performed using a
−1
125 mm diameter cannon. The yaw-induced projectile deflection was recorded at 5 000 s , and the failure mode and
penetration depth of the projectile were obtained. Through a comparative analysis of anti-penetration experimental results
between semi-infinite concrete targets and UHS-SS-reinforced targets, the influences of ultra-high mechanical performances
and the spherical yaw-inducing structure on the deflection and fragmentation of the projectile were disclosed. The test results
reveal that at a penetration velocity of 400 m/s, the dimensionless penetration depth of the UHS-SS target is 0.11, and the
penetration resistance of the UHS-SS target is about 9 times that of C40 concrete. The anti-penetration performance of UHS-SS
is significantly enhanced in comparison to that of the ordinary concrete target. Furthermore, as the projectile penetrates the
