【摘要】：随着制造业市场需求的变化,大规模设计模式已经不再适应当今的的市场,现在的市场已经和以前不同,客户提出了各种各样的个性化需求。对市场做出快速的响应是企业的核心竞争力。在这种情况下,形成了大规模定制模式,模块化设计、可重用设计得到了广泛的应用,产品数据管理(PDM)成为了主要的设计平台。CAD模型作为一类重要设计资源,其数量随着三维CAD技术推广而剧增。为了提高设计资源的可重用性,从而减少企业产品开发的成本,论文围绕构建可重用设计资源、可重用设计资源的管理、可重用设计资源的编码等关键技术展开研究。具体内容如下： (1)通过对PDM软件系统的体系结构和设计重用单元进行深入的研究以后,提出了基于PDM的可重用设计体系结构。 (2)探讨了基于PDM平台构建可重用设计资源的关键技术,并对各种设计技术对设计重用的支持性进行了分析。结合具体企业的产品给出了具体的构建方法。 (3)针对企业中不同的设计资源,采用不同的方法来进行构建,同时探讨了如何在PDM平台上对设计资源进行管理,对基于PDM的产品开发模式也进行了研究。详述了基于PDM平台之上重用设计资源的管理方法、设计重用单元的引用模式及面向检索的数据属性设计方法。 (4)通过企业信息化需求的分析,探讨了企业编码的过程中一些尤其值得注意的问题。结合企业的产品特点,提出了设计资源的编码的原则,设计了设计资源编码体系,最后基于EPDM平台开发了可重用设计资源的编码器,提高了企业的可重用设计资源的利用。上述研究方法在企业得到了应用,实践证明构建基于PDM的可重用设计资源,减少了企业的冗余数据,缩短了企业的交货期,提高了产品的设计效率,最终提高了企业的核心竞争力。
[Abstract]:With the changing demand in the manufacturing market, large-scale design patterns are no longer adapted to today's market, and the market is different now than before. Customers put forward a variety of personalized requirements. Rapid response to the market is the core competitiveness of the enterprise. In this case, a mass customization model, modular design, reusable design has been widely used. Product data Management (PDM) has become the main design platform. As a kind of important design resources, the number of PDMs has increased dramatically with the popularization of 3D CAD technology. In order to improve the reusability of design resources and reduce the cost of enterprise product development, This paper focuses on the construction of reusable design resources, reusable design resources management, reusable design resources coding and other key technologies. 1) after deeply studying the architecture and design reuse unit of PDM software system, a reusable design architecture based on PDM is proposed. This paper discusses the key technologies of building reusable design resources based on PDM platform, and analyzes the support of various design technologies for design reuse. The concrete construction method is given in combination with the products of specific enterprises. 3) aiming at different design resources in enterprises, different methods are used to construct them. At the same time, how to manage design resources on PDM platform is discussed. The management method of reusing design resources based on PDM platform, the reference pattern of design reuse unit and the method of data attribute design for retrieval are also studied in this paper. Based on the analysis of enterprise information demand, some problems in the process of enterprise coding are discussed. According to the characteristics of enterprise products, the principle of design resource coding is put forward, and the design resource coding system is designed. Finally, the encoder of reusable design resources is developed based on EPDM platform, which improves the utilization of reusable design resources in enterprises. The above research method has been applied in the enterprise. The practice proves that the construction of reusable design resources based on PDM reduces the redundant data of the enterprise, shortens the delivery time of the enterprise, and improves the design efficiency of the product. Finally, improve the core competitiveness of enterprises.
