中文摘要:
      目的 对木托盘静载堆码时的力学性能进行理论分析和有限元模拟。方法 建立木托盘顶铺板和纵梁板的力学模型,通过理论计算获得选用松木和杨木LVL 2种不同材料时的最大应力和最大挠度;按国家标准建立木托盘有限元模型,进行网格划分、施加载荷和约束后,获得选用松木和杨木LVL 2种不同材料时的最大等效应力值和最大变形量,并与理论分析结果进行对比。结果 理论分析和有限元分析结果规律一致,最大应力均出现在中间纵梁板上,最大变形均发生在顶铺板上,且数值差距较小,2种分析方法均合理可行。结论 该研究为木托盘的性能分析提供了有效的方法。
英文摘要:
      The work aims to carry out theoretical analysis and finite element simulation on mechanical property for wood pallet at stacking under static load. The mechanical model of top planking and stringer plate of wooden pallet were established, and the maximum stress and maximum deflection of two different materials (pine and cottonwood LVL) selected were obtained by theoretical calculations. After the finite element model of wooden pallet was established according to national standards, and then mesh was divided, load was applied and constrained. The maximum equivalent stress and maximum deformation of two different materials (pine and cottonwood LVL) selected were obtained. The differences between theoretical calculation and simulation results were compared and analyzed. The regularity of theoretical analysis and finite element analysis was in consistency with each other. The maximum stress occurred on the middle stringer plate and the maximum deformation occurred on the top planking. The gap of theoretical analysis and finite element analysis was smaller. These two methods were feasible. The study provides an effective method for the property analysis of wooden pallets.
