摘要
研究了在高速动能弹打击下，不同夹层结构所构成的复合装甲的抗弹性能。采用有限单元法及MSC软件MSC．PATRAN和LS—DYNA进行数值模拟。首先，从夹层构形方面建立3层问隙装甲模型，中问层分别为平板夹层、波纹夹层和蜂窝夹层；通过不同配置，分别研究并对比了平板夹层、波纹夹层和蜂窝夹层构形的抗弹性能。分析结果表明，可以从改善夹层构形、厚度配比等方面来提高复合装甲的抗弹性能。
The purpose of this paper is to study the anti-eroding performance of composite armors with different interlayer structures under high-speed projectile impact. Finite element method and MSC Software （MSC. PATRAN and LS-DYNA） are used in the paper. The armor models are founded with flat inter-layer, ripple interlayer and beehive interlayer. The anti-eroding performances of three kinds of interlayer are studied. The results quantificationally show that interlayer structure and thickness distribution ratio have great influence on the anti-eroding performance of composite armors. Therefore, the simulation has great importance in engineering. It not only can evaluate the performance of the composite armors of a main battle tank and put forward feasible improved projects, but also can provide an effective and economic new approach to designing the armors of the new tank based on the obtained results.
