The work aims to carry out theoretical analysis and finite element simulation on mechanical property for wood pallet at stacking under static load. The mechanical model of top planking and stringer plate of wooden pallet were established, and the maximum stress and maximum deflection of two different materials (pine and cottonwood LVL) selected were obtained by theoretical calculations. After the finite element model of wooden pallet was established according to national standards, and then mesh was divided, load was applied and constrained. The maximum equivalent stress and maximum deformation of two different materials (pine and cottonwood LVL) selected were obtained. The differences between theoretical calculation and simulation results were compared and analyzed. The regularity of theoretical analysis and finite element analysis was in consistency with each other. The maximum stress occurred on the middle stringer plate and the maximum deformation occurred on the top planking. The gap of theoretical analysis and finite element analysis was smaller. These two methods were feasible. The study provides an effective method for the property analysis of wooden pallets.
