Design for assembly ( dfa ) is an important enabler in concurrent engineering 摘要面向装配的设计是并行工程中的一项重要的使能技术。
Concurrent engineering is one new kind of design theory and developing technology of product development . in the theory of the concurrent engineering , design for assembly is one of the important tools 并行工程是一种全新的设计理念与产品开发技术,面向装配的设计是并行工程的重要工具之一。
The cad method based on template integrated with the assemble - oriented means owns both merit . in the dissertation , the concept of the press tool template is given in the way of formalization . the template is applied in the development of the cad system of press tool 基于模板的cad设计方法与面向装配的设计方法的结合综合了两种方法的优点,文章形式化的给出了冷冲压模板的定义,并将其应用于冷冲模cad系统的开发,讨论了系统的实现。
Running side by side engineering technology reflects this thought , people constantly develop the support tool dfx ( design for x ) , such as design for manufacture , design for assembly , etc . the application of these tools has made some effects in shortening the products " development cycle , but there is no substantive progress in reducing of the cost of the products 并行工程技术正体现了这种思想,人们不断地开发并行工程的支持工具dfx ( designforx ) ,如面向制造的设计dfm ( designformanufacture ) ,面向装配的设计dfa ( designforassemble )等,这些工具的应用在缩短产品开发周期方面取得了成效,但是在产品成本降低方面没有实质性的进展。
Assembly relationships , assembly hiberarchy and assembly restraints are analyzed . the assembly modeling methods of bottom - up and top - down are put forward . the author summarizes the characteristics of panels , investigates the modeling technology of free - form curve and surface ; the algorithm of surface joining and surface blending is also analyzed 阐述了面向装配的设计方法的运行模式和体系结构;详细探讨了装配建模的主要内容,分析了装配模型的装配关系、装配层次关系以及装配约束,对装配模型的信息组成进行了介绍,提出了自下向上的装配建模方法和自顶向下的装配建模方法。
