Aiming at the modal characteristic prediction problem of orthog-onal rib-stiffened sandwich plates in the condition of simply sup-ported, the reinforced core increases the complexity of the struc-tural control equation. Therefore, this paper establishes a com-plete theoretical model based on the theory of orthotropic sand-wich plate, and then carries out finite element analysis and exper-imental test research. Compared with the theoretical calculations, the simulation and experimental natural frequencies are within the error range of 5%, and the three can effectively verify each other’s accuracy, which can guide the improvement of theoretical prediction and simulation analysis.
