托盘结构设计一直采用经验设计方法，其结构的合理性有待研究。通过SolidWorks对托盘进行了建模和参数化设计，并运用其集成的Simulation仿真分析功能对所建立的模型进行了有限元分析。通过与托盘试验原型测试对比，验证了分析的正确性和有效性。最后通过SolidWorks的优化功能对托盘模型进行了优化设计，得到了以安全系数为约束条件的托盘上连板的最优厚度。该方法可行、有效，为托盘结构分析和优化设计提供了一条新的思路。

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.
