In this article, to study the local compression deformation of aluminum foam sandwich (AFS) panels by orthogonal method, two-dimensional random simulation models of AFS panels were constructed by C++ language combining with ANSYS software, and four parameters, including aluminum foam core's geometrical characteristic parameters porosity P and pore size R and experimental parameters loading force F and local compressing length L, were simultaneously considered. Furthermore, the dependences of the local compression deformation of AFS panels on the above-mentioned parameters were investigated by range analysis and variance analysis means and the related mechanisms were described. The results of range analysis confirmed that factors influencing local compressive deformation of AFS panels are in turn: porosity P, pore size R, local compressing length L, loading force F, in other words, P > R > L > F. Furthermore, variance analysis results showed, compared to loading conditions, geometrical parameters of samples were more influential on the local compressive deformation of AFS panels.
