Structural design of pallet always uses empirical method, and its rationality needs further investigation. The modeling and parameterized design of pallet was carried out by using Solidworks, and then finite element analysis of the model was carried on by using its integration function. The analytical results were validated with the prototype test of pallet. Ultimately, the optimum design of pallet was processed via the optimization toolbox of SolidWorks, and the best thickness of top deckboards for pallet was obtained by the optimal design which meets safe coefficients as constraint conditions. It was proved that the method is feasible and available. The purpose was to provide a method for structural analysis and optimum design of pallet.
