含预埋梁蜂窝夹层结构数值仿真与试验研究

含预埋梁蜂窝夹层结构是在纯蜂窝结构基础上改进得到的全新结构形式，综合了蜂窝结构和桁条铆接结构的优点，但该类结构的载荷分布形式以及失效模式缺乏相关研究。针对上述问题，结合国内在研尺寸最大的含预埋梁铝蜂窝夹层结构，采用层合板加筋方法进行了数值仿真，设计全尺寸物理试验对结构性能进行了试验验证。通过数值仿真和试验对比，验证了层合板加筋方法模拟含预埋梁蜂窝结构的准确性，同时研究了该类结构的载荷分布和失效模式，并为同类结构设计提供了参考依据。

Numerical simulation and test study on honeycomb structure with embedded stringers

The stringer-embedded honeycomb structure, which contains the advantages of both honeycomb structure and riveted structure, is an innovative structure improved from honeycomb. However, the relative research on load distribution and failure modes on this type of structure is inadequate. Depend on the largest aluminum honeycomb sandwich structure under researching, beam-reinforced laminate method was used for numerical simulation. Further to this, a full-size physical test was also designed. Good agreement has been achieved in the comparison between the numerical simulation and test, which verifies the beam-reinforced laminate method. This paper also investigated load distribution and failure modes of stringer-embedded honeycomb structure, and it can be regarded as a design reference for similar structure.
