摘要: 针对细长薄壁弹冲击下的高强钢-混凝土复合结构厚度极限计算问题,开展了细长薄壁弹冲击复合靶试
验,基于试验结果分析了复合结构防护机理和弹体结构的破坏模式;在原有厚度极限计算模型的基础上,考虑了弹体
结构强度这一关键因素,提出了新的厚度极限计算模型,并对相关参数经验性进行了讨论。研究结果表明:高强钢-混
凝土复合结构的防护机理在于高强钢提供材料强度,混凝土背板提供支撑刚度,二者优势互补;由于细长薄壁弹体在
冲击过程中易发生压缩胀裂破坏,计算模型必须考虑弹体结构强度对冲击效应的影响;复合结构的设计需同时兼顾高
强钢力学性能和复合结构厚度极限 2 个方面。此外,本文计算模型存在参数具有经验性、计算结果偏保守等不足,后
续研究还需对该模型加以修正。

Abstract: The study aims to solve the problem of calculating the thickness limit of high-strength steel-concrete composite
structures under the impact of slender thin-walled projectiles, a key consideration for protective engineering design. A series of
impact tests on composite targets were carried out. These targets were composed of different high-strength steel plates and
concrete backplates. Slender thin-walled projectiles were launched with a gas gun at controlled velocities, and the impact
process were captured by high-speed cameras. The resulting damage to the structures and the failure modes of the projectiles
were analyzed using both non-destructive and destructive testing methods. Based on test results, the protective mechanism of
the composite structures and the failure modes of projectiles were analyzed. An improved thickness limit calculation model
was then developed. Unlike the original model, this new model incorporated the structural strength of slender thin-walled
projectiles, considering their wall thickness, material yield strength, and geometric dimensions, and was established based on
force equilibrium and energy conservation principles. The results show that the high-strength steel in the composite structures
provides material strength to resist penetration, while the concrete backplate offers support stiffness. As slender thin-walled
projectiles are prone to compression and expansion cracking during impact, their structural strength must be factored into the
calculation model. Moreover, the design of composite structures should consider both the mechanical properties of high-
