The work aims to study the effects of all factors on the analysis precision when the finite element software was used to simulate the bending performance of wooden pallets. The theoretical analysis and finite element simulation of the bending performance of wooden pallets were made. The theoretical deformation values were obtained through the calculation of deck mechanical model. The pallet model created by Creo software was imported into Ansys Workbench for analysis, and the finite element simulation values were obtained. The control variable method was used to change the element type and meshing method, and the results and theoretical calculations were compared and analyzed. The error between overall displacement results and theoretical value obtained by the default software element type and meshing method was 2.97%. Through the adjustment of each influence factor, the error between the displacement result and the theoretical value of top deck was 0.02%. In the case of the same number of elements, the analysis precision of the higher-order element is better than the lower one. Hexahedral element is superior to the tetrahedral element. With the other setting conditions unchanged, the refined mesh can improve the analysis precision.
