中文摘要:
      目的 研究拼装箱有限元模型的建模方法和结构参数对力学性能的影响。方法 以某胶合板拼装箱为研究对象, 采用有限元软件平台Ansys建立该拼装箱的有限元模型, 并通过跌落试验验证该模型应用于拼装箱力学性能仿真的可行性。在此基础上, 对拼装箱的3个设计参数(钢边的厚度、 胶合板厚度、 胶合板材质) 分别进行动态跌落测试和静态堆码实验的仿真分析。其中钢边厚度分别是0.4,0.8, 1.2 mm; 胶合板厚度分别是6, 8 mm; 胶合板材质为杨木、 桦杨木和桦桉木。结果 通过动态和静态数值仿真分析, 采用6 mm桦杨木胶合板, 同时保持钢边为0.8 mm厚度的镀锌钢为最优方案。结论 采用Shell 163薄壳单元模拟钢边和胶合板, 并用Solid 164实体单元模拟托盘的拼装箱建模方案是可行的。结果应用于拼装箱优化设计中, 可得到满足要求且成本最低的方案设计。
英文摘要:
      The aim of this work was to study the finite element modeling method of the splice box and the effect of structural parameters on the mechanical properties. Using the finite element software platform Ansys, the finite element model of the plywood splice box was established, and the feasibility of the model in simulation of mechanical property of splice box was verified by the drop test. On this basis, simulation analysis of the dynamic drop test and static stacking test was conducted by changing three design parameters of the splice box (steel strip thickness, plywood thickness and plywood material). The steel strip thickness was 0.4, 0.8, 1.2 mm; the plywood thickness was 6 and 8 mm respectively; the plywood materials were poplar, birch & poplar, birch & eucalyptus. The dynamic and static numerical simulation analysis revealed that the 6 mm birch poplar plywood together with galvanized steel with a steel edge of 0.8 mm thickness was the optimal solution. The splice box modeling method of using Shell 163 thin shell element to simulate steel and plywood, and Solid 164 solid element to simulate tray box was feasible. The results were applied to the optimization design of the splice box, and the design scheme meeting the requirements and with the lowest cost was obtained.
