Research And Realization On The Virtual Assembly System Technology

As a key technology of the Virtual Manufacture, Virtual Assembly attracts concerns from both academic and industrial fields. The virtual assembly environment is built by data model of the product to simulate and analyse the assembly process, to evaluate the assembly schema, and to find the assembly defaults as early as possible. Also the assembly information can be feeded back to the designers.Using this technology, the traditional physical prototype of the product can be replaced with the digital prototype. It can not only be favourable to the deployment of Concurrent Engineering, but also can greatly shorten the product's design period, reduce the product's design costs, and improve the product's commercial competitive ability.So virtual assembly has important theoretical and practical value to the implement of Agile Manufacture , Virtual Manufacture and other advanced manufacture model.Be based on the theory of Virtual Assembly and its application technology, this paper makes further analysis and study on theory of Virtual Assembly and its key technology. The study that associates with reality has developed by all means degree, which makes the study and application of the theory of Virtual Assembly keep up with the development pace of advanced technique of manufacture. Accordingly the system of the theory of Virtual Manufacture comes into integrative, in deed the engine design and manufacture of engine truly achieves automated.The study of Virtual Assembly will make the application of Virtual Manufacture Technology further broad in practice. This way reduces the cost of study and application, advances the quality of assembly, shortens the period of product development, brings the ultimate benefit, provides a new consider to the study of Virtual Assembly Technology. At the same time, the study of Virtual Assembly Technology tends towards multivariant yet.
