摘要/Abstract

摘要： 为了研究铝蜂窝夹层板在低速冲击下的动力学响应,通过有限元仿真软件ANSYS/LS-DYNA分析了半球头圆柱低速冲击铝蜂窝夹层板的损伤变形,建立了含蒙皮、蜂窝芯和胶层的铝蜂窝夹层板精细化仿真模型,通过与文献试验结果对比,验证了模型的准确性,并研究了铝蜂窝芯单元尺寸、高度以及金属、碳纤维增强复合材料(CFRP)两种蒙皮材料对蜂窝夹层板冲击响应的影响。结果表明:铝蜂窝芯单元尺寸越大,夹层板的刚度和稳定性越低;芯层高度对吸能的影响较小;胶层对吸能的影响不可忽略;相对于铝蒙皮,CFRP蒙皮铝蜂窝夹层板的吸能效果较好。

Abstract: In order to study the dynamic response of aluminum honeycomb sandwich plate under low speed impact, the damage deformation of low speed impact aluminum honeycomb sandwich plate with hemispheric head cylinder was analyzed by finite element simulation software ANSYS/LS-DYNA. The fine simulation model of aluminum honeycomb sandwich plate with face sheet, honeycomb core and cohesive layer was established. The accuracy of the model was verified by comparison with the test results in the literature. The impact response of aluminum honeycomb core unit size and height as well as metal and carbon fiber reinforced composite (CFRP) were studied. The results show that the sandwich plate of larger size of aluminum honeycomb core unit has lower stiffness and stability. The core height has little effect on energy absorption. The influence of cohesive layer on energy absorption cannot be neglected. The energy absorption performance of aluminum honeycomb sandwich panel with CFRP face sheet is better than that of aluminum face sheet.

Key words: aluminum honeycomb sandwich plate, low speed impact, finite element method, dynamic response
