【Abstract】 Virtual design technology is a new research field in recent years, which combined many kinds of advanced technologies and is one of key point who is focused by science and technology field and enterprises. Tripod universal joint, a kind of new constant velocity coupling, whose design and manufacture are the key points of coupling industry. In this paper, we give some introduction on virtual design system executer of tripod universal coupling based on application of VRML. We integrate VRML and Java to design this dummy system and establish the frame of this virtual design system so that it realized the modeling with parameters, three-dimensional display and movement simulation.With this paper, we describe the performance procedures of virtual design system for slider coupling from the facets of its theory, ways and processes. We also give some introduction about whole design and model components on how to realize the target of software system and design frame. We create this system by Java computer language, in order to make the system more interactive, expanded the date transfer of control principle using Script node, JSAI and EAI, and Java has a good communication with computer and some other computer software, so that our virtual design system is easier to transfer the data from system to Access data severed by JDBC-ODBC bridge, which will let the system create the VRML files and perform the coupling created under virtual system with many functions such as modeling with parameters, three dimension display, movement simulation and etc. For easier understanding of this system, we list some examples in this paper introduction.With this system, the clients can make a quickly design and movement simulation of coupling. It is proved that it can short the coupling development time and enhance the design characters under this system with the application of Java and VRML.更多还原
