基于可靠性的重型托盘系统设计和优化程序
摘要：最近出货的重型货物或设备正在成为一个新的领域，而托盘则相当重要。 在这篇文章中，各种材料的比较表明，层压单板木材是重型包装行业的理想选择。针对各种随机参数托盘，提出了一种混合可靠性优化设计方法为托盘系统的可靠性设计提供有效的计算工具。 利用一阶二阶矩法，得到了分量和系统失效概率的分离与组合。包括几个案例研究来说明计算程序，以及讨论构件的维度和数量的影响。 采用实验方法设计，各参数的灵敏度显着，实现了整个系统的优化。 为了降低成本，回收和标准化在未来值得考虑。

The reliability-based design and optimization procedures for a heavy-duty pallet system
Abstract：Shipping heavy-duty goods or equipment is being a new sector recently, and the pallet is rather important. In this article,a comparison of various materials revealed that laminated veneer lumber was ideal for heavy-duty packaging industry.For various pallets with random parameters, a hybrid reliability optimization design method was proposed, which aimedto provide an effective computational tool for reliability design of pallet system. With first-order second-momentmethod, the separation and combination of component and system failure probabilities were obtained. Several case studies were included to illustrate the computational procedures, as well as to discuss the effects of dimension and quantityof members. Using design of experiment method, the sensitivities of each parameter were significant, and the optimization of whole system was realized. To reduce the cost, recycling and standardization were worth considering in thefuture.
Keywords：Pallet, reliability, first-order second-moment method, laminated veneer lumber, design procedures[1]
