The mechanical equations with bending and bending coupling effects are established for the asymmetric honeycomb sandwich panel, and the thermal deformation is analyzed. In order to validate the analysis results, the thermal deformation experiment under atmospheric pressure and high temperature was designed. The experimental methods, data acquisition equipment and experimental procedures were introduced. The experimental results show that the calculated results are in good agreement with the actual deformation, which verifies the rationality of the antenna plate design and the correctness of the finite element model.
