【摘要】 随着社会的不断发展,工业制造水平的不断提高,工业制造目标已经不仅仅是大批量的标准化的工业零部件,而更多是小批量富有个性的生活用品和艺术品。比如最近火热的3D打印技术,消费者可以打印任意输入模型,在家里制造自己想要的模型。这些技术极大拉进了普通个体与工业成型制造的距离,然而,耗材的成本,模具模型的重复使用,仍然是一个问题。随着成型制造技术下探到消费领域,众多设计也得到了极大满足。设计已不仅仅面向普通使用,也越来越考虑到便携性,比如可拆卸橱柜、折叠自行车。这些设计使物体便于折叠或者拆卸,从而易于运输和储存。然而无论是面向普通使用还是面向便携性,设计者都希望物体的结构在使用的时候尽可能稳定,而且在拆卸的时候尽可能迅捷。所以结构组装的稳定性与拆卸的便捷性始终是一个重要话题。本文面向结构的组装与拆卸,针对三维壳体模型,提出一种基于自锁自拆卸结构的装配体。装配体分为若干可拆卸的活动组件,并通过自锁形成稳定结构。结构含有一个关键组件,未移除关键组件,其他组件被锁住,整个装配体处于稳定状态;移除关键组件,其他组件解锁,按照设计顺序在重力驱动下自行拆卸。本文主要贡献是开创性地构造性自锁自拆卸结构,并面向结构稳定性和活动性,分析并优化其自锁自拆卸性能。最后,本文使用3D打印技术打印并验证结果。本文所提出的结构与理论可以应用在制造领域和设计领域,为定制模具、任意模型的拆卸、组装、重复使用提供了一种可行的解决方案。更多还原

【Abstract】 With the continuous development of society and the improvement of industrial manufacturing,industrial manufacturing not only targets large quantities of standardized industrial parts,but more small quantities,fullly personalized works of art.For example,the recent hot 3D printing technology,consumers can print any input model at home to create their own model.These technologies greatly pulled into the ordinary individual and industrial molding manufacturing distance.However,the cost of supplies and the re-use of mold model is still a problem.The molding technology is improving,many designs have also been greatly implemented.Design has not only design for the general use,but also increasingly consider the ease of portability,such as removable cabinets,folding bike.These structures are designed to facilitate folding or disassembling the object,making it easy to transport or store.However,whether it is for the use or for the portable,designers want the structure of the object when used as stable as possible,and in the demolition of the time as fast as possible.So the stability of structural assembly and the ease of disassembly has always been an important topic.This paper presents a three-dimensional shell,which is an interlocking and self-collapsing structure of the assembly.The assembly is divided into a number of removable components,and forms a stable interlocking structure;structure contains a key component,the key components is in present,the other components are locked,the entire assembly is in a steady state;remove the key components,other components can self-collapse under the gravity.The main contributions of this paper are propose of interlocking and self-collapsing structure,the analysis of structural stability and activity and optimization of interlocking and self-collapsing structure.Last but not least,we performed the experiments and use 3D printing technology to print and verify the results.The structure and theory proposed in this paper can be applied in the field of manufacturing and design,and provide a feasible solution for the removal,assembly and reuse of custom molds arbitrary models.更多还原
