摘要	An equivalent modeling method for honeycomb sandwich structure is presented in this paper. Honeycomb core is regarded as an interlayer and orthogonal anisotropic solid elements are used to model it, while the panels of honeycomb sandwich structure are represented by shell elements. This method not only controls model size and ensures computational efficiency, but also solves the problem that two-dimensional model cannot represent the internal stress distribution and local deformation. Based on the orthogonal anisotropy of honeycomb and the actual cellular size, 9 independent elastic parameters of the interlayer are given, so that the physical properties of the interlayer are described completely. In the example, the displacement errors under typical static loadcases are less than 3.12% and the frequency errors of the first six orders are less than 4.07%, compared with the precise model. A modal tapping test was carried out on a payload mounting panel with honeycomb sandwich structure. By comparing the test data with the analysis data of the equivalent model, it was shown that the frequency errors of the first six orders were all within 5%, and the analysis modes were consistent with the experimental fitting modes, which further verified the validity of the equivalent method.
