The work aims to confirm whether the galvanized steel panel is suitable for the logistics metal pallet package and study the mechanical property of its bending deformation. The metal panel was modeled based on SolidWorks software. The centroid position model and the method of solving moment of inertia of the panel were established based on the relevant knowledge of mechanics. At the same time, the displacement bending deformation simulation was carried out on the panel with a length ranging from 600 mm to 1200 mm in Ansys Workbench. The theoretical calculation of the maximum deflection of the panel was deduced. The accurate centroid position yp=10.334 mm and its moment of inertia Izp=1.372×10-8 m4 of the panel, as well as the maximum displacement deformation theory and the simulation values of the panels of different lengths were obtained. The theoretical calculation method for the bending deformation of the metal pallet panels is provided, which further confirms the durability and practicability of the metal pallet panel in logistics package. The study provides the basis for the discussion on the pallet's mechanical property and structural optimization.
