【摘要】：产品数据管理(PDM)是一门管理与产品相关的信息（包括电子文件、数字化文档、数据库记录等）和与产品相关的过程（包括工作流流程和工程更改）的理论与技术。它为设计人员提供了贯穿产品全生命周期的信息管理平台，并且能为产品设计和制造搭建一个企业级的并行化协同环境。本文以中德变速器公司的产品设计为应用背景，从公司的需求出发，采用量化比较的评估方法，提出了选用基于CAXA的企业PDM系统规划设计的解决方案。结合企业的组织架构及管理模式，对企业PDM系统的信息模型进行研究，建立符合企业特点的PDM系统信息模型，包括：企业人员组织模型，建立人员与角色的对应关系，并按企业的需求进行角色权限设置；产品数据模型将企业的产品图纸在PDM系统中以产品树的形式进行管理，其他类型的文件在PDM系统中以文档树的形式管理。研究企业的工作流模型，将企业的图纸审批发布流程、文件编制审批流程、设计更改流程在PDM系统中结构化，实现这些流程的自动化。最后详细介绍了公司PDM系统实施及实例应用情况，，总结了实施后给公司带来设计图纸、文档管理更规范、更标准，设计流程实现自动流转的效果，评价了PDM给公司带来的设计人员工作效率提升、产品设计及制造成本有效降低、提高无形技术资产重用率方面的效益。
[Abstract]:Product data management (PDM) is a theory and technology for managing product related information (including electronic documents, digital documents, database records, etc.) and product-related processes (including workflow processes and engineering changes). It provides designers with an information management platform running through the product lifecycle and builds an enterprise-level parallelized collaborative environment for product design and manufacturing. Taking the product design of China and Germany transmission company as the application background, starting from the company's demand and adopting the evaluation method of quantitative comparison, this paper puts forward a solution to choose the enterprise PDM system planning and design based on CAXA. Combined with the organization structure and management mode of the enterprise, the information model of the enterprise PDM system is studied, and the information model of the PDM system which accords with the characteristics of the enterprise is established, including: the organization model of the enterprise personnel, the corresponding relationship between the personnel and the role, The product data model manages the product drawings in the form of product tree in the PDM system, and the other types of files are managed in the form of document tree in the PDM system. The workflow model of the enterprise is studied. The drawing approval and release process, the document approval process and the design change process are structured in the PDM system to realize the automation of these processes. Finally, the implementation of PDM system and its application are introduced in detail, and the effect of automatic flow of design flow is summarized, which brings to the company design drawings, more standardized document management and more standard design flow. The efficiency of designers brought by PDM is evaluated, the cost of product design and manufacture is reduced effectively, and the efficiency of reusing intangible technical assets is improved.
