产品的研发和设计在企业的发展中起着十分重要的作用,在产品研发和设计过程中,采用先进的或理想的设计方法有助于提高产品的“先天性”优良品质。近百年来,国内外科技工作者已提出70多种产品设计方法。10多年来,在吸取这些设计理论和方法优点的基础上,提出一种在科学发展观指导下的产品系统化设计方法。该方法概括以下8方面的要点:① 原来的产品设计的原5项要素质量(Quality, Q)、成本(Cost, C)、生产周期(Time, T)、环境(Environment, E)和服务(Serve, S)应该用6项设计要素思想(Idea, I)、Q、C、T、E和S来代替,增加产品设计的正确指导思想I;② 用4个更具体的设计步骤,即3I(Investigation)调研、7D(Design)规划、1+3+X实施和3A(Assessment)检验来代替传统的产品设计步骤;③ 将产品的性能分为结构性能、使用性能和制造性能等三种主要性能;④ 提出绿色设计宜用和谐设计来取代,按线性系统的常规设计方法在一些特殊的情况下应该用深层次的设计方法来取代;⑤ 进一步说明顶层设计和系统化设计的概念和内涵;⑥ 对完整性与非完整性技术系统进行讨论;⑦ 写出产品设计目标、设计内容和设计方法的关联方程;⑧ 写出产品设计质量的理论表达式。上述设计方法已应用于多种产品的设计,均取得良好的效果。 相似文献

Traditional computer-aided design (CAD) and product lifecycle management (PLM) tools have their limitations in supporting quick-to-market, mass-customized product development environments. The present paper proposes a general integrated framework of design knowledge representation and develops a knowledge-based intelligent system (KBIS) to facilitate dynamic design reasoning. Owing to the increasing complexity of product design, the traditional design (knowledge) rules can no longer help facilitate complex product development, which requires flexible design knowledge adoption and collaborators’ interaction during design inference processes. Therefore, this research enhances the abilities of smart collaborative design reasoning. A conceptual architecture for the KBIS is presented to enable a collaborative design community to reason feasible design parameters and to integrate all sub-system designs of a product. Finally, a case study of designing an air compressor and its sub-system (V-type belt) is presented to demonstrate the unique features of the KBIS. 相似文献

The core competitiveness to survive severe business environments comes from the capability of well-defined design chains across enterprises, not the capabilities of individual enterprises. The collaboration in the design chains, however, is difficult due to the inherent complexity such as diverse design processes and dynamic design environments. To settle the collaboration problems in the design chains, a design chain collaboration framework (DCCF) is proposed in this paper. The DCCF is composed of three reference models capturing the different views of design chain collaboration: design process reference model (DPRM), service component reference model (SCRM), and technology and standard reference model (TSRM). As the DCCF adapts the Object Management Group’s (OMG) metadata architecture, the processes in the design chain can be extended when it is necessary. Using the proposed framework, design managers can integrate their design processes from the conceptual phase to the application development phase. The DCCF can also serve as a virtual basis to improve design processes continuously in order to enable collaboration and to breed innovation . 相似文献

Today's manufacturing environment forces manufacturing companies to make as many product variations as possible at affordable costs within a short time. Mass customisation is one of most important technologies for companies to achieve their objectives. Efforts to mass customisation should be made on two aspects: ① To modularize products and make them as less differences as possible; ② To design manufacturing resources and make them provide as many processes variations as possible. This paper reports our recent work on aspect ②, i.e. how to design a reconfigurable manufacturing system (RMS) so that it can be competent to accomplish various processes optimally; Reconfigurable robot system (RRS) is taken as an example. RMS design involves architecture design and configuration design, and configuration design is further divided in design analysis and design synthesis. Axiomatic design theory (ADT) is applied to architecture design, the features and issues of RRS configuration design are discussed, automatic modelling method is developed for design analysis, and concurrent design methodology is presented for design synthesis. 相似文献

针对大规模定制与产品平台战略技术,模块化设计是一种有效的设计方法,而模块的划分是该方法的关键.文中结合公理设计与设计结构矩阵,利用独立公理进行产品功能划分,建立产品设计矩阵,再结合设计矩阵与设计结构矩阵,构建产品设计关联矩阵,然后利用可拓聚类算法对该关联矩阵进行聚类运算,以此来完成产品设计的模块划分;并将所划分的模块用独立公理再次做功能独立性分析,最终确定产品模块.最后以桥式起重机起重小车模块划分为例,验证了该设计方法有效性和可行性,提高了产品设计效率,降低了设计成本. 相似文献

Concurrent or collaborative engineering (CE) has inspired research in the area of design decomposition, which facilitates
the concurrency of product lifecycle functions from the earlier stage of the product development process and reduces the complexity
of a design problem. The decomposition-based design, on the other hand, necessitates various integration efforts for recombining
the decomposed design problems. This is the second of a two-part paper proposing a multi-agent system (MAS) framework for
integrated product design in a computer network-oriented CE environment. Part II discusses the applications of the proposed
MAS framework to concurrent engineering design. The proposed framework realises the systematic and timely design integrations
between multi-functional/cross-functional team members in a dynamic design environment, by enabling model integration, solution
integration and tool integration. The proposed design agents make the problem-specific engineering models or heterogeneous
design tools interoperable and network-accessible, and also provide the interaction spaces for communicating, integrating
or coordinating the individual design solutions. Throughout the paper, the proposed system is illustrated with a successful
implementation of a continuously variable transmission (CVT) design problem over the Internet . 相似文献

仪器仪表结构虚拟设计研究 总被引:2,自引:1,他引:1
长期以来,在仪器仪表的开发过程中,其结构造型设计往往落后于其功能设计,成为缩短仪器仪表设计周期的瓶颈.原因在于结构设计所需数据来源于功能设计,并且整个设计过程常常会出现反复.本文提出在仪器仪表结构造型中,通过在虚拟空间中建立设计对象的原始模型来获得设计对象的细节,从而使结构设计和修改更加自由和快捷,缩短开发周期.本文利用OpenGL(OpenGraphicLibrary)和MFC(MicrosoftFoundationClass)开发了3DInstrument虚拟设计系统来完成仪器仪表结构的设计和修改.该系统可以建立一个虚拟三维空间,仪器仪表的结构模型就建立在该空间中,开发人员由此可以检验仪器仪表机构设计的有效性. 相似文献
