摘要本文分析了圆柱形破片侵彻纤维增强复合材料三明治板的过程，基于能量守恒定律分别对圆柱形破片侵彻面板、复合材料夹层和背板三个阶段中消耗的能量进行了理论推导，建立了圆柱形破片侵彻纤维增强复合材料三明治板的计算模型，并得到了剩余速度的计算公式，令剩余速度等于零，即可得到弹道极限。将计算模型得出的结果与试验结果进行了对比，验证了计算模型的可行性与有效性。本文的计算模型可以为钢／纤维增强复合材料／钢复合装甲结构的抗侵彻设计提供指导。

Abstract：In this work, the process of a cylindrical fragment penetrating a fiberreinforced composite sandwich plate was analyzed. Based on the law of energy conservation, the energy consumption in the three stages of the cylindrical fragment penetrating fiber reinforced composite sandwich plate was theoretically derived, including the penetration of panels, the penetration of composite laminated, and the penetration of back. Then the analytical model of the cylindrical fragment penetrating the fiber reinforced composite sandwich plate was built, and the calculating formula of residual velocity was obtained. The ballistic limit could be obtained when the residual velocity was equal to zero. Comparing the results calculated by the analytical model with experimental results, the feasibility and effectiveness of the analysis model was verified.

Key words： composite armor high speed fragment ballistic limit;analytical model
