【摘要】 本文针对在大规模定制中客户个性化产品配置设计完成后,为了使客户能够快速的查看配置产品装配的效果,技术人员能够快速对配置产品的进行预装配分析,从而对客户的个性化产品装配的可行性和装配的可靠性进行判断,加快产品的上市时间,增加企业的竞争力,提出了基于模块化的并纱机数字化预装配系统开发与研究的课题。本文首先对基于实例的模块化产品配置设计方法进行了研究,研究了模块的划分原理,建立模块的接口矩阵和数据结构,提取并纱机的配置参数并建立配置参数与模块的映射关系。随后研究了数字化预装配模型,并建立了基于模块化的产品数字化预装配的信息模型。文章重点对基于骨架模型的数字化预装配方法进行了研究,首先研究了基于产品族的骨架模型,阐述了骨架模型的功能及在数字化预装配中骨架模型的作用,以并纱机的产品族为例建立了基于产品族的骨架模型,并利用骨架模型对并纱机模块进行了装配;接着详细阐述了快速替换模块技术和尺寸驱动两个数字化预装配变型设计的关键技术,通过定义了替换模块的参照标签,确定了替换模型在整个装配体中的装配空间位置及空间拓扑关系,通过尺寸驱动完成并纱机产品锭数与产品模块的关联。最后研究了装配干涉检查,在Pro/E中对产品可装配性进行了分析。最后利用Visual Basic6.0、Pro/ENGINEER 2.0、Automation GATEWAY4.2等进行了系统的开发,以并纱机为例对系统做了验证。更多还原

【Abstract】 After completion of the configuration design in the mass customization, the effect of customized product assembly is rapidly showed, and the technicians could quickly analyze the configure products to judge the feasibility and the reliability of the pre-assembly. So speed up product time to market and increase the competitiveness of enterprises. For these intentions, the research and development on the digital pre-assembly system of double-wire machinery based on modularization is putted forward.Firstly, design methods of modular product configuration based on case are studied. The theory of module partition is studied. And the module interface matrix and data structure are established. After the configuration parameters of double-wire machinery are extracted. The mapping relations between the configuration parameters and module are established. Subsequently by studying the digital pre-assembled model, the information model of the products pre-assembly based on module are established.The thesis focused on the research of digital pre-assembly methods based on skeleton model. Firstly the thesis study the skeleton model based on product family. The functions of skeleton module are expatiated in the digital pre-assembly. After the skeletons of double-wire machinery are established, the modules of double-wire machinery are assembled by the skeletons. The rapid replacement model and driver size, which are the key technologies of the digital pre-assembled variant design, are elaborated. The assembly room location and spatial topology of a replacement module is determined in the entire assembly by defining reference tags. The relation between spindle and module of double-wire machinery is established by driving size. Finally the assembly interference check is studied. And the assembly of the product is analyzed in the Pro/E.Finally, by the use of Visual Basic6.0, Pro/E, Automation GATEWAY4.2 the system was developed. By taking double-wire machinery for example the system isvalidated.更多还原
