【摘要】 本文从产品市场需求状况的转变分析开始,以纺织机械制造企业为背景讨论了当前制造业在产品的上市周期、生产成本和满足用户多样化、个性化等方面的不足。在企业逐步接受大规模定制生产模式理念的环境下,着重提出了旨在提高快速响应用户需求能力、缩短产品设计周期、降低成本、设计出满足用户个性化产品方案的快速设计理念及其必要性。在国内外专家学者和制造企业从不同的技术角度对快速设计技术研究基础上,本文提出了面向产品族的快速设计思想及其主要内容和定义:面向产品族快速设计是以模块化设计为手段、以产品族为数据组织形式、综合利用多种现代设计方法的一种符合现代市场需求的先进设计方法。本文的主体部分主要讨论了面向产品族快速设计系统的系统体系结构、系统设计对象的研究、系统模块的开发和实例介绍等。 一、分析了快速设计的原理和目标,在面向产品族快速设计系统流程、系统功能体系和技术体系的基础上,提出系统的总体体系结构,包括技术层、功能系统层和数据层。 二、论述了产品族的概念,并在产品族和产品模型中融入模块化思想,提出了基于模块化的结构-原理-功能产品族模型,并以此作为产品族模块划分方法和基于矩阵的模块系列规划理论依据。对粗纱机进行产品族规划,并在分析产品功能结构特点的基础上进行产品族模块规划。讨论了快速设计系统的设计信息构成,提出并建立统一的关系型对象数据模型,为构建企业满足快速设计的设计资源库奠定基础。 三、详细论述了组成面向产品族快速设计系统的分系统模块,包括用户需求管理模块、基于实例推理的模块化产品变型设计模块和产品设计资源管理模块的功能组成、技术实现和体系结构。在设计系统中引入了QFD(质量功能配置)、CBR(基于实例推理)、参数化设计等各种现代设计分析方法,解决了从快速、准确响应用户个性需求到快速产生产品设计方案的各个技术环节。利用C++Builder平台、Microsoft SQL Sever数据库管理系统和Pro/Engineer三维CAD软件构建具有集成性和开放性的快速设计软件系统。并以纺机产品模块化方案设计系统(TMPDS)为例,介绍了快速设计系统的各个功能模块。 最后,论述了本文的主要结论,针对现有研究阶段的不足,提出了今后的研究方向与展望。更多还原

【Abstract】 With the analysis of current situation of market requirements, this thesis discussed the deficiencies of manufacturing enterprises on producing cycle, cost and customer satisfaction, etc based on Textile Machinery manufacturing enterprises. In the fact that manufacturing enterprises are about to accept the theory of Mass Customization, the thesis presented the need of Rapid Design methodology which focus on rapid response of customer requirements, shortening of product design period, cost reducing and individualized product output. Built on the various studies of Rapid Design Methodology by national and international experts, the thesis proposed a Rapid Design methodology oriented to product family, which is an advanced design approach for modern market requirements. The modularization is regarded as the core technique of this methodology along with the data organization form by product family. The system structure of product family-oriented rapid design system, design object and software system components developing were presented on the body.1. On the analysis of theory and objective of Rapid Design, the thesis provided flow, functional and technical elements of product family-oriented rapid design system, and established whole system structure including technique, function and data layers.2. The thesis introduced the module theory to product family and product model after the definition of product family was clarified. It proposed function-principle-structure product family model on the module, which served as the basis of modularization and systematization. The case study of Fly Frames was presented in terms of modular design. Furthermore, the thesis studied information constitution of system and put forward a uniform object data model for the relational resources database.3. Software system components were detailed such as customer requirements management module, case based variant design module and design resources management module in terms of functional, technical and structural studies. The thesis introduced QFD, CBR and parameterized design, etc to the design system in order to carry out each technical part, the range from rapid and accurate response of customers to rapid design results. Developed an integrated and open software system for Textile Machinery rapid design based on software platform as C++Builder, Microsoft SQL Sever, Pro/Engineer, thesis described each functional module.The thesis made the conclusion in the end and proposed the prospect of this area.更多还原
