Pallets and corrugated boxes are ubiquitous in the global supply chain. However, the interactions that exist between the boxes and pallets are ignored during the pallet design process resulting in the over designing of pallets and the waste of raw materials. The goal of this research is to understand how pallet performance is affected by headspace, box size, and base design across multiple support conditions using block class wooden pallets. Headspace and base design had no effect on pallet deflection for the experimental weights used throughout testing. However, the effect of box size was significant on pallet deflection across multiple support conditions. The effect was greatest for lower stiffness pallets and low‐stiffness support conditions (racking across the width; RAW) with up to a 50% reduction in pallet deflection observed by switching from small to large boxes on a very low‐stiffness pallet. Evaluation of pressure mat data showed an increase in the redistribution of pressure away from the center of the pallet and toward the supports as box size increased. The redistribution of pressure toward the supports is known as load bridging and validates the observed reduction in pallet deflection as a function of box size. The results indicate that incorporating this effect of packages into current pallet design practices could result in more effective and cheaper pallet designs.

根据包装尺寸和托盘刚度研究块状托盘的负载桥接效应,根据包装尺寸和托盘刚度研究块状托盘的负载桥接效应

托盘和瓦楞纸箱在全球供应链中无处不在。但是,在托盘设计过程中忽略了盒子和托盘之间存在的相互作用,这导致了托盘的过度设计和原材料的浪费。这项研究的目的是了解在使用块状木质托盘的多种支撑条件下,顶空,盒子尺寸和底座设计如何影响托盘性能。对于整个测试中使用的实验砝码,顶空和底座设计对托板挠度没有影响。但是,箱子尺寸对多种支撑条件下的托盘挠度影响很大。对于较低刚度的托盘和低刚度的支撑条件(在整个宽度上倾斜;RAW),通过在非常低刚度的托盘上从小盒子切换到大盒子,可以将托盘挠度降低多达50%。压力垫数据的评估显示,随着包装箱尺寸的增加,从托板中心向支撑的压力重新分布增加。压力向支撑物的重新分布称为负载桥接,它验证了所观察到的托盘挠度随盒尺寸的变化而减小。结果表明,将包装的这种影响纳入当前的托盘设计实践中可能会导致更有效和更便宜的托盘设计。压力向支撑物的重新分布称为负载桥接,它验证了所观察到的托盘挠度随盒尺寸的变化而减小。结果表明,将包装的这种影响纳入当前的托盘设计实践中可能会导致更有效和更便宜的托盘设计。压力向支撑物的重新分布称为负载桥接,它验证了所观察到的托盘挠度随盒尺寸的变化而减小。结果表明,将包装的这种影响纳入当前的托盘设计实践中可能会导致更有效和更便宜的托盘设计。,托盘和瓦楞纸箱在全球供应链中无处不在。但是,在托盘设计过程中忽略了盒子和托盘之间存在的相互作用,这导致了托盘的过度设计和原材料的浪费。这项研究的目的是了解在使用块状木质托盘的多种支撑条件下,顶空,盒子尺寸和底座设计如何影响托盘性能。对于整个测试中使用的实验砝码,顶空和底座设计对托板挠度没有影响。但是,箱子尺寸对多种支撑条件下的托盘挠度影响很大。对于较低刚度的托盘和低刚度的支撑条件(在整个宽度上倾斜;RAW),通过在非常低刚度的托盘上从小盒子切换到大盒子,可以将托盘挠度降低多达50%。压力垫数据的评估显示,随着包装箱尺寸的增加,从托板中心向支撑的压力重新分布增加。压力向支撑物的重新分布称为负载桥接,它验证了所观察到的托盘挠度随盒尺寸的变化而减小。结果表明,将包装的这种影响纳入当前的托盘设计实践中可能会导致更有效和更便宜的托盘设计。压力向支撑物的重新分布称为负载桥接,它验证了所观察到的托盘挠度随盒尺寸的变化而减小。结果表明,将包装的这种影响纳入当前的托盘设计实践中可能会导致更有效和更便宜的托盘设计。压力向支撑物的重新分布称为负载桥接,它验证了所观察到的托盘挠度随盒尺寸的变化而减小。结果表明,将包装的这种影响纳入当前的托盘设计实践中可能会导致更有效和更便宜的托盘设计。
