摘要

采用试验与有限元分析相结合的方法研究了复合材料蜂窝夹层结构的抗冲击性能。基于Vumat子程序建立其三维渐进失效准则,通过试验来验证仿真模型的准确性。利用精确仿真模型来进一步对不同参数下蜂窝夹层结构的抗冲击特性进行研究。结果表明:冲击能低于一定值时,冲击峰值力随冲击能的增加而增加,当冲击能超过该值时,冲击峰值力将会稳定不变;冲头直径越小,冲击峰值力越小,蜂窝夹层结构吸收能越大;蒙皮厚度的增加可使蜂窝夹层结构抗冲击性能增强,但蒙皮厚度对吸能特性影响较小。

Abstract

The impact resistance of composite honeycomb sandwich structure is studied by means of experiment and finite element analysis. The three-dimensional progressive failure criterion is established based on the VUMAT subroutine, and the accuracy of the simulation model is verified by experiments. The accurate simulation model is used to further study the impact resistance of honeycomb sandwich structure under different parameters. The results show that when the impact energy is lower than a certain value, the impact peak force increases with the increase of impact energy, and when the impact energy exceeds this value, the impact peak force will be stable; the smaller the impactor diameter is, the smaller the impact peak force is, the greater the absorption energy of honeycomb sandwich structure is; the increase of skin thickness can enhance the impact resistance of honeycomb sandwich structure, but the skin thickness has a greater impact on the energy absorption characteristics small.
