文档介绍：I 摘 要 传统瓦楞纸箱的配纸方法多依靠经验,费时费力,并且容易造成包装不足或过度。本课题引入价值工程的概念,结合技术和经济两方面综合优化瓦楞纸箱配纸设计,不仅提高了纸箱的物理性能,而且节约了成本。该方法为一种适度包装方法,为瓦楞纸箱的配纸设计提供了一种新思路,主要研究内容如下: ( 1 )在瓦楞纸箱配纸过程中引入价值工程,首先介绍了价值工程的概念和一般工作程序, 然后阐述了其应用在纸箱配纸中的意义和作用, 最后总结了运用价值工程进行瓦楞纸箱配纸方案优选的工作程序。价值工程既考虑了技术的先进性和可行性,又考虑经济上的合理性和实现性,为优选模型的建立提供了理论指导。( 2 )以瓦楞纸箱为研究对象,运用价值工程对纸箱的功能进行定义和整理得到原纸强度是影响瓦楞纸箱物理性能的主要因素。试验研究原纸强度对纸箱物理性能的影响, 并利用 SPSS 对其结果进行分析。分析表明,在恒温恒湿的条件下,瓦楞芯纸的环压强度对纸箱的抗压强度影响很大, 原材料对单瓦 B 楞纸箱抗压强度的影响排序为芯纸环压强度?面纸环压强度?里纸环压强度;原材料对双瓦 BC 楞纸箱抗压强度的影响最大的为芯纸 2,最小的为夹心纸,其它因素的排序为里纸环压强度?面纸环压强度?芯纸 1 环压强度。( 3 )温湿度保持不变的情况下,瓦楞芯纸的耐破度对瓦楞纸箱的耐破度几乎没有影响。试验表明,面纸稍大于里纸对单瓦 B 楞纸箱耐破度的影响;原材料耐破度对双瓦 BC 楞纸箱耐破度的影响排序为面纸耐破度?里纸耐破度?夹心纸耐破度。( 4 )根据价值工程进行多方案优选的工作程序,以瓦楞纸箱的功能分析为核心,以提高瓦楞纸箱的价值为目的,建立了瓦楞纸箱配纸方案的优选模型。运用模型进行实例分析,采用 Matlab 对模型进行编程,求解得到价值系数 V 最大时的配纸方案,分析结果合理, 证明了优选模型的可行性。关键字: 瓦楞纸箱,抗压强度,耐破度,配纸,价值工程 II ABSTRACT Traditional matching paper method of corrugated box relies on the experience, which is time-consuming, easy to insufficient and excessive packaging. Considering both tec hnology and economics, the conception of value engineering was introduced to the paper to reduce the cost and improve the value. The method provi des a new way to paper optimum design for its appropriate. The main contents are as follows: First, the conception, work pro cedure, meaning and functions of value engineering are introduced in paper design. And the selection of multi-program of corrugated box is su mmarized. The value engineering takes into account not only advance a nd feasibility of technology, but also rationality and possibility, which provides theore tical foundation for the optimization model. Second, the subject of study is corrugated box. Af ter corrugated box functions defined and arranged, th e paper determines raw materials strength as the main factor of physical properties. Tests are carried out to study the effect of raw materials strength and corrugated box physical properties. The analysis which got by means of SPSS show that, th
