| 摘 要： | 采用两种有限元模型和工程方法分别对复合材料蜂窝夹层结构在压缩、剪切载荷作用下的总体稳定性进行了计算,根据各计算结果与试验结果进行了对比分析。结果表明:对于承受压缩载荷的结构,采用工程计算法能够较好的预估结构的屈曲临界载荷,而对于承受剪切载荷的结构,采用三维有限元法能较好的计算结构的屈曲载荷。

| Abstract: | Two finite element models and engineering method are used to analyze general stability of honeycomb sandwich structure with compressed or shearing load. The results indicate that engineering method can estimate the buckling load of structure with compressed load, and three-dimensional finite element method can calculate the buckling load of structure with shearing load. |
