Research On Technologies Of Wind Turbine Virtual Assembly Based On Web

According to requirements of wind turbine workshop production and development of virtual assembly technology, a simulation platform based on Web was designed by using of Virtual Reality Modeling Language VRML, JavaApplet and ASP.net technology, and it realizes the virtual design platform to be unconcerned. The product assembly operations, parts information management, assembly and disassembly process animation display and other functions can be achieved by Different user roles respectively. The platform can be easily integrated into existing network platform of university or corporate, which can improve the intelligibility of the assembly process and guidance dramatically; meanwhile, parts design information can be combined with the assembly process. The platform can carry on the interactive control of assembly process, which can provide effective help for teaching or training of maintenance personnel of wind turbine, so it have a high practical value. Therefore, it is of great significance to study the virtual assembly technology of wind turbine.Key technologies of virtual assembly based on Web were studied by this paper. The structure of virtual assembly system on Web environment was established; Idea of product process model adapting to wind turbine assembling is presented by introducing the notions of assembly tasks and bind the assembly relationship and design information together. Finally, a whole assembly model is presented. Virtual assembly route layout and assembly process emulation is realized through VRML animation functions based on event-driven and transformation; the assembly operations of parts is completed and Human-computer interaction is realized in Web environment through Coordination of EAI (external authoring interface) of VRML and the communication mechanism of JavaApplet; Combined database SQL-server, VRML and ASP technology, visualization and product information management of components functions in the network environment is put to effect, which include to add, delete, the nodes of product hierarchy tree and modify the node changes. Finally, each function and application effect of the proposed technology was verified by wind turbine simulation experiment.
