【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。
[Abstract]:Objective to study the modeling method of the finite element model and the influence of structural parameters on mechanical properties of the assembling box. Finite element software platform Ansys is used to establish the finite element model of the assembly box, and the feasibility of applying the model to the mechanical performance simulation of the assembly box is verified by drop test. Three design parameters (thickness of steel edge, thickness of plywood, material of plywood) were simulated by dynamic drop test and static stacking experiment. 1.2 mm; The thickness of plywood was 6 ~ 8 mm; The plywood was made of poplar, birch poplar and birch eucalyptus. Results through dynamic and static numerical simulation, 6 mm birch poplar plywood was used. At the same time, the best scheme is to keep the galvanized steel with a thickness of 0. 8 mm. Conclusion Shell 163 thin shell element is used to simulate the steel edge and plywood. It is feasible to use Solid 164 entity unit to simulate the pallet assembly box modeling scheme. The result can be applied to the optimal design of the assembly box and the lowest cost scheme can be obtained when it is applied to the assembly box optimization design.
