中文摘要:
      目的 通过对不同托盘结构进行分析,选出满足托盘承载性能要求的轻量化的铝合金托盘结构。方法 利用SolidWorks软件对不同类型托盘进行三维建模,并用Ansys Workbench对其进行静力分析,对比不同类型托盘应力、变形及安全系数,选出结构最优的铝合金托盘,并对其尺寸进行优化。结果 方案C的托盘质量、纵梁应力、纵梁变形和纵梁安全系数分别为19.68 kg, 247.39 MPa, 3.41 mm和1.13,优于其他类型托盘,对其铺板厚度及纵梁相关尺寸进行优化后,其质量减少22%,纵梁安全系数提高20.4%。结论 铺板厚度为1 mm,垫块厚度为1.5 mm,以及其他相关尺寸分别为5, 5, 30 mm的方案C铝合金托盘为载荷一定条件下的最优结构。
英文摘要:
      The work aims to select a lightweight aluminum alloy pallet structure satisfying the requirements of pallet load-carrying performance based on the analysis of different pallet structures. 3D modeling of different types of pallets was carried out with SolidWorks software, the static analysis was carried out with Ansys Workbench, and the stress, deformation and safety factor of different types of pallets were compared. Then, the optimal aluminum alloy pallet was selected and its size was optimized. In scheme C, the pallet quality, and the stress, deformation and safety factor of the stringer were 19.68 kg, 247.39 MPa, 3.41 mm and 1.13, respectively, better than other types of pallets. After the thickness of top deck and the relevant sizes of the stringer were optimized, its mass was reduced by 22% and the safety factor of the stringer was increased by 20.4%. The aluminum alloy pallet in scheme C in which the thicknesses of the top deck and cushion are 1 mm and 1.5 mm, and other relevant sizes are 5, 5 and 30 mm respectively is the optimal structure when the load remains constant.
