目的 市场上的托盘箱普遍根据经验设计,其设计周期长,成本高。 拟研究利用有限元模拟托盘箱性能的可行性。 方法 先利用三维软件 Solidwokrs 完成托盘箱的建模,再导入有限元分析软件Workbench 模拟其货架弯曲性能,根据模拟结果修改模型,直至满足要求后进行打样制造,然后进行实际托盘箱样品的实验。 结果 托盘箱货架弯曲的实验结果和模拟结果总体上吻合度较高,托盘上 5 个试验位置挠度的相对误差随着载荷的增大而逐渐减小,并趋于稳定。 结论 使用有限元软件 Workbench 来进行托盘箱结构的设计和性能模拟分析是可行且有效的。

Objective The design of box pallet is mostly experience-based, which has long design period and high cost. The aim of this study is to check the feasibility of simulation of box pallet performance using finite element analysis. Methods The modeling design of pallet was carried out by using Solidworks, and then finite element analysis of the model was carried on by using Workbench. The model was modified based on simulation results until it met the requirements, and then a sample was prepared for the racking bending experiment. Results The results showed that the simulation results of racking bending performance of the box pallet were similar with the experimental results. The relative error of five points decreased with the increase of pressure and was finally stabilized. Conclusion It was confirmed that the design of box pallet and simulation of racking bending performance of box pallet by workbench was feasible.
