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层间隙装甲模型,中间层分别为平板夹层、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 anti-ballistic performance of composite armor formed by different sandwich structures was studied under the attack of high-speed kinetic energy bomb. The finite element method and MSC software MSC.PATRAN and LS-DYNA were used for numerical simulation. First of all, a three-layer gap armor model is established from the aspect of sandwich configuration. The middle layer is flat sandwich, corrugated sandwich and honeycomb sandwich respectively. Through different configurations, the anti-elastic properties of flat sandwich, corrugated sandwich and honeycomb sandwich are studied and compared respectively . The analysis results show that the composite armor can improve the anti-ballistic performance of the composite armor from the aspects of improving the configuration of the sandwich and the thickness ratio.
