本文根据Hellinge-Reissner变分原理,用混合-杂交等参夹芯层板单元对复合材料夹芯结构翼面的静、动力特性进行有限元数值分析,并与相应的试验结果作了比较,证明分析是成功的。
According to the Hellinge-Reissner variational principle, the static and dynamic characteristics of the sandwich composite sandwich panel are analyzed by finite element method (FEM) with mixed-hybrid and other parametric sandwich panels. The results are compared with the corresponding experimental results Analysis is successful.
