目的 基于 Workbench 设计和分析塑料托盘结构的可靠性和可行性。 方法 通过建立塑料托盘的有限元模型,对其施加相应载荷,模拟塑料托盘试验时的受力情况,分别计算托盘在均载堆码、叉举、底铺板、弯曲下的挠度值,并与实验结果进行比较。 结果 塑料托盘 4 个挠度值的实验结果和模拟结果相对误差在 10% 以内。 结论 采用 Workbench 对托盘进行受力分析具有可靠性和可行性。

Objective To use Workbench to design plastic pallet structure and analyze its reliability and feasibility. Methods Finite element model was established for the plastic pallets and stress load was applied to simulate the load condition of plastic pallet during experiment, and the deflection values of the pallets under various conditions of stacking, fork lifting, bottom deck bending and bending tests were calculated, and compared with experimental results. Results The results showed that the simulation results were similar with the experimental results, and the relative error between experimental and simulated values was within 10% . Conclusion It was confirmed that it is reliable and feasible to analyze the performance of plastic pallets using Workbench.
