【摘要】 今天的市场正在向个性化消费环境迅速转变,一方面,消费者的行为更加具有选择性,“客户化、小批量、快速交货”的要求不断增加；另一方面,产品交货周期、生命周期却越来越短,这对企业传统的产品设计制造方式带来了巨大挑战。在此背景下,个性化产品定制技术与三维参数化设计技术应运而生并取得长足发展。个性化产品定制技术开创性地允许客户参与到产品设计开发的全过程,从而最大限度地满足客户的多种需求；三维参数化设计及虚拟装配技术则大幅提高企业生产设计效率,提高了企业对客户需求的响应速度。因此,如何将二者优势特点相结合,实现既满足客户需求又提升产品设计效率的双重效果,正成为现代企业生产设计制造追求的目标。目前,国内外学者分别对个性化产品定制和三维参数化设计理论及其在工程上的应用进行了广泛研究,然而由于个性化产品定制与三维参数化协同设计出现时间尚短,将三维参数化设计与个性化产品定制技术相统一,把二者技术优势相结合的设计思想还不够成熟,其理论体系和关键技术还需要进一步探索。因此,研究基于个性化产品定制的三维参数化设计理论和实践对发展国内先进制造模式具有重要现实意义。本文在相关项目基金资助下,提出了基于个性化产品定制的三维参数化设计思想,并就其理论基础、设计思想、关键技术等开展了一系列研究工作。本文首先综述了国内外个性化产品定制、三维参数化设计研究的发展概况,并对研究现状进行了比较全面的总结。在此基础上,围绕企业实际需求建立了基于个性化产品定制的三维参数化设计系统。本论文具有创新意义的主要研究工作有如下几个方面：(1)提出了针对单件小批量生产模式下大型机械产品的个性化定制及其参数化协同设计系统工作流程,研究了构建网络化制造环境下基于个性化产品定制参数化设计系统框架结构的问题,并提出了基于Agent定制模块框架结构和基于OLE三维参数化设计系统的二次开发思想。(2)提出建立了一种基于多色图理论的产品配置模型,并用蚁群优化算法求解本文提出的根据客户定制需求生成响应的产品配置方案模型,同时针对蚁群优化算法容易陷入局部最优解的缺点进行了改进。(3)采用VC++语言开发了基于嵌入式技术的三维大型压缩机参数化设计模块。在此基础上,应用虚拟现实技术对压缩机三维实体装配过程进行了分析,对装配动态演示、装配顺序、装配零件系统编号、装配效率等进行了系统研究。(4)本文对复杂零件、装配体的参数化设计方法进行了研究,并应用描点样条曲线技术、程序驱动绘制草图技术,在Solidworks环境下对某大型压缩机关键部件叶轮部分进行了精确三维实体造型,为后续利用Ansys进行气体流动等工程分析奠定了坚实基础。(5)采用JSP技术开发基于B/S架构的了客户端系统,采用Java3D技术、Socket编程进行了基于C/S架构设计端和服务器端系统的设计和实现,同时开发了关系型数据库用于存储系统零件库、客户订单、配置方案等。更多还原

【Abstract】 The market today is changing towards the personalized consumption environment rapidly. On one hand, consumers’ behavior is more selective, the requirements of "customization, small batch, delivering fast" are increasing constantly; on the other hand, products deliver cycle and lifespan are getting shorter and shorter, all of these bring tremendous challenges to the enterprises’ traditional product design and production mode. Under this background, the personalized product customization technology and three-dimensional parameter designing technique arise at the historic moment and obtain tremendous development. That the customers participate in the whole process of the product design and development are allowed by using customizing technology creatively, and this mode meets the customer’s many kinds of demands to the maximum extent; and the application of three-dimensional parametric design and virtual assembly technology promotes the efficiency of enterprise’s designing capability greatly, and it has improved the response speed of enterprises to customers’ demand. Then, how to combine the two advantages and characteristics, realize the double effects of meeting customers’ demand as well as promoting the efficiency of product design, is becoming the pursued goal of producing, designing and manufacturing of modern enterprise.At present, the domestic and international scholars are separately carrying on extensive research on the personalized product customization and three-dimensional parameter design theory and their applications in engineering projects, but because the personalized products customize and the three-dimensional parameter coordinary design both have short history, and the design method to unify the three-dimensional parametric design and individual product customization technology and combine the technological advantage of two Design philosophy is not ripe enough, and its theoretical system and key technology need further exploring. Therefore, study of the customized three-dimensional parameter design theory and practice on the basis of the personalized product has important realistic meanings of developing the advanced manufacturing mode at home.Under the fund subsidy of relevant projects, this paper proposes the three-dimensional parameter design theory based on the personalized products customization, and has launched a series of research work on its theoretical foundation, design philosophy, key technology, etc. This paper surveys the development overview of domestic and international personalized product customization, three-dimensional parametric design at first, and has carried out a more overall summary in the current research situation. On this basis, the personalized products customization based three-dimensional parametric design system is set up around the enterprise’s actual demand.The mainly innovation work of this paper has such following aspects:(1) The work flow of the personalized customization and parametric collaborative design system of large mechanical product in small batch product mode is proposed, and the problems of personalized product customization based parametric design system in networked manufacturing environment are studied, and the redevelopment methods of Agent customization based module framework and OLE based three-dimensional parametric design system are presented, too.(2) This paper proposes a product configuration model based on polychromatic graph theory, and the product configuration project model according to the cosumers’ customization demand prososed in this paper is solved by ant colony optimization algorithm, while the local optimal solution faults about the ant colony optimization algorithm are improved.(3) A three-dimensional large-scale compressor parametric design module based on embedded technology is developed with Microsoft VC++developing language.
