摘　　要：基于虚拟现实建模语言的产品数据模型,可满足协同设计中快速网络传输、跨计算机辅助设计系统和跨平台的要求。对协同设计过程中几个主要阶段设计了相应的优化技术,即设计操作独立化、传输操作参数化、传输模型最优化,显著提高了虚拟现实建模语言模型协同设计的实时性。基于以上优化技术,开发了虚拟现实建模语言环境下的协同设计支持系统———基于虚拟现实建模语言的虚拟装配系统。最后,给出了该系统的应用实例。Virtual Reality Modeling Language （VRML） model could satisfy requirements in collaborative design such as fast transmission over Internet, cross--platform, and cross--CAD systems. To remarkably enhance the feasibility of real--time performance of VRML model in collaborative design, optimization technologies were proposed correspondingly towards each phase of collaborative design, which were independent design, parametric transmission, optimal model transmission. Based on these optimization technologies, a VRML--based collaborative design support system called VIAVRML was developed. Finally, the application example was provided to demonstrate the improvements in real--time performance.
