Due to the difficulty of direct finite-element modeling for honeycomb sandwich panels, it is more common to apply equivalent modeling theories. It is necessary to compare their equivalent precision and then to determine the method with the best equivalent performance so as to prepare for the application in satellite solar arrays. The first 10 natural frequencies are obtained by analyzing the dynamic characteristics of sandwich panel theory model, honeycomb panel theory model, and equivalent panel theory model. The equivalent errors of different equivalent methods are obtained by comparison with the analysis results of real honeycomb panel model. Then, the sandwich panel theory and the Hoff theory with high precision are used to simulate the solar array panel. The two methods are further verified and compared by simulation and experiment. Finally, the sandwich panel theory with the highest accuracy is selected to simulate the vibration response of the solar array panel based on the above work. By comparing the frequency response analysis results with the test results, it is found that the maximum acceleration response error is within 7%, and the corresponding frequency error of the main direction is within 3%. The comparison between random analysis results and test results shows that the root mean square response errors of acceleration in three directions are within 13.7%. It is proved that the sandwich panel theory has high accuracy in the honeycomb structure. Based on the background of a specific space project, this study innovatively applies the test results to compare several typical equivalent theories of honeycomb sandwich panels so as to get a theory with the highest equivalent precision. The final conclusion has been applied to the design of related space products and proved to be feasible. This provides important reference and basis for the structural design of the satellite.

由于蜂窝夹芯板直接有限元建模的困难，应用等效建模理论更为普遍。有必要比较它们的等效精度，然后确定具有最佳等效性能的方法，以便为在卫星太阳能电池阵列中的应用做准备。通过分析夹心板理论模型，蜂窝板理论模型和等效板理论模型的动态特性，可以获得前10个固有频率。通过与实际蜂窝板模型的分析结果进行比较，得出不同等效方法的等效误差。然后，采用高精度的夹心板理论和霍夫理论对太阳能电池板进行了仿真。通过仿真和实验进一步验证和比较了这两种方法。最后，基于上述工作，选择了精度最高的夹心板理论来模拟太阳能电池板的振动响应。通过将频率响应分析结果与测试结果进行比较，发现最大加速度响应误差在7％以内，主方向相应的频率误差在3％以内。随机分析结果与测试结果的比较表明，三个方向上加速度的均方根响应误差在13.7％以内。实践证明，夹层板理论在蜂窝结构中具有较高的精度。根据特定太空项目的背景，本研究创新地将测试结果应用于蜂窝夹心板的几种典型等效理论进行比较，从而获得具有最高等效精度的理论。最终结论已应用于相关空间产品的设计，并被证明是可行的。这为卫星的结构设计提供了重要的参考和依据。
