摘要: |
协同设计目前已经成为解决复杂产品设计问题的关键技术之一。在分析了现有协同设计问题的基础上,提出通过构建虚拟PDM(VPDM, Virtual PDM),应用交换特征增长数据的方法,来解决企业间异构PDM、CAD应用系统的协同设计问题。给出了虚拟PDM的定义,并介绍了基于虚拟PDM进行协同设计的基本原理。建立了基于虚拟PDM的协同设计框架,分析了虚拟PDM系统的各组成部分。描述了Express表达的操作模型、统一特征模型,并将其映射到数据库。描述了虚拟PDM环境下基于特征增长的协同设计流程。通过系统所述的方法,研制的原型系统初步实现了两类CAD和PDM软件之间的协同设计。 |

Abstract: |
Collaborative Design has currently become one of key technologies to solve complex product design problems. Based on new problems of existing collaborative design, the study puts forward a method of building VPDM, and uses an exchanging method of feature-adding data to resolve problems of heterogeneous PDM and CAD systems among enterprises. Firstly, a definition of VPDM was presented, and the basic principle of VPDM-based collaborative design was introduced. Secondly, the framework of VPDM-based collaborative design was proposed and each components of VPDM were analyzed. Then, the operation model and the unified feature model represented by Express-G were built and mapped into database. Finally, the feature-adding collaborative design sequence diagram was described in VPDM environment. By using the above method, the prototype system developed in the study enables the collaborative design in two kinds of CAD and PDM software in principle. |
