| 摘 要： | 金属靶板的抗侵彻性能一直以来都是被重点关注的研究领域。为明确结构参数对钢/铝组合结构抗步枪弹垂直侵彻性能的影响，建立了步枪弹侵彻钢板和铝板的数值计算模型，并通过弹道冲击实验进行了验证；进而基于数值计算模型分析了相同厚度下钢-铝、铝-钢的组合形式、靶板间距对组合靶板抗侵彻性能的影响。仿真结果表明：相同厚度下，钢板在前的组合形式优于铝板在前的靶板，但不同组合形式的层板间距对其抗侵彻性能影响较小；另外，比较了不同初速度下钢-铝厚度比的变化对组合靶板的抗侵彻性能影响，均呈现出随厚度比增加，抗侵彻性能先降低后增加的趋势，最终趋于一个稳定值。变化过程中存在一个抗侵彻性能最差的低点，在结构设计中应尽可能避开。最后，依据R-I公式拟合了仿真数据，得到了步枪弹侵彻钢-铝组合结构的弹道极限公式。研究结果可为组合靶板的抗侵彻性能设计和人员、物资防护提供参考。

| Abstract: | The anti-penetration performance of metal target plate has always been a focus of research. In order to clarify the influence of structural parameters on the vertical penetration resistance of steel/aluminum composite structures, numerical calculation models of steel and aluminum composite structures were established and verified by ballistic impact tests. Based on the numerical model, the influences of the combination form of steel-aluminum, al-steel and target spacing on the penetration resistance of the composite target with the same thickness were analyzed. The simulation results show that under the same thickness, the combination form of steel plate in front was better than the target plate with aluminum plate in front, but the different combination form of laminar spacing has little influence on its anti-penetration performance. In addition, the influence of the thickness ratio of steel to aluminum on the penetration resistance of the composite target plate at different initial velocities was compared. The penetration resistance of the composite target plate decreases first and then increases with the increase of the thickness ratio, and finally reaches a stable value. There is a low point with the worst penetration resistance during the change process, which should be avoided as much as possible in structural design. Finally, the trajectory limit formula of musketeer projectile penetrating steel-aluminum composite structure was obtained by fitting the simulation data according to THE R-I formula. The research results can provide reference for the design of anti-penetration performance of composite target plate and the protection of personnel and materials. |
