| The development of modern science is becoming more globalization, networking, virtualization and intelligent. And modern product design requires mutual cooperation about each several part of it. It is highly dependent on information sharing and work synchronization. In these situation, along with the development of Virtual Reality technology and the application of computer network, distributed Virtual Reality system base on Internet became a new technology.Based on Product Lifecycle Management technology, Virtual Reality technology and computer network, the issue analyzed the practicability of the application on network of Virtual Reality technology. Then, it put forward a solution to achieve a cooperative work system, which is based on Virtual Reality technology and network environment and Product Lifecycle Management technology. After that, it completed research and design of the display and interaction function of this system.The system which provided the methods throughout the whole product lifecycle is based on B/S three-layer structure. It made models by VRML, and achieved interaction ability through JAVA language. Because of these, the system can break through the limitation of time and space.The paper introduced Web-based virtual reality technology, distributed virtual reality technology first, then studied Product Lifecycle Management technology, after that, it gave us the solution of the system which is motioned in the article. It also gave out the requirement analysis, structure, flow chart and system modules of that. The paper described the realization of VRML display module and interaction module, then discussed the optimization of the system, such as increased the transmission speed, and improved the stability of it. After showed two different applications to the users, the paper summarized the function, strongpoint and application of this system, and point out some problems which need to be discussed in the near future. |
