虚拟产品开发技术与开发系统模型研究

Research on Developing Technique and Developing System Model of Virtual Products

叙述了虚拟产品开发的意义及其所依赖的支撑技术。在认真考虑了虚拟产品开发的各种因素基础上建立了开发系统的模型和结构，并阐述了一些重要的概念，如产品数字原型和虚拟原型，虚拟产品开发技术和系统，ＣＡＸ和虚拟产品开发，模拟和虚拟现实，虚拟产品数据和ＳＴＥＰ标准等。本文还简述了虚拟产品技术的应用和开发系统原型的研制。

This paper introduces the important basis of Virtual Product Development (VPD) and techniques. The model and structure of VPD System (VPDS) are proposed and many concepts (digital poduct, VP, CAX, VPD techniques, VPDS, simulation and virtual reality, STEP and VP database) are discussed. The application of VPD techniques and the developing VPDS prototype are also presented.
