Research On Integrated Modules Of Assembly Modeling Method

Virtual manufacturing technology is the direction of advanced manufacturing technology in the next decade. With advances in science and technology, urged the computer software and hardware technologies to enhance, virtual environments such as virtual manufacturing and virtual assembly techniques have been related to rapid development. Virtual assembly is a virtual product development technology cell technology, virtual manufacturing its own cost as the highest technical content of the most important a part, has been more concern and attention of researchers.In this paper, the theory and technology of virtual assembly, based on the tolerance of the virtual assembly model theory and key technology research, improve the tolerance of meta-information. In which the product information and assembly information model components conducted discussion and in-depth study by the VB language development and build a database of realized at any time add, modify, delete, and query functions to facilitate the users to call and see. Through the key assembly and gear assembly and the cylinder straightness tolerance analysis, the Deform virtual simulation software, taking into account various factors, and finally comes down to the tool error compensation, Thereby reducing the impact of the actual processing of tolerance, while in the assembly sequence based on some of the assembly process simulation technology.Finally, the optical encoder assembly as an example, the virtual assembly simulation, to extract the outline of the actual tolerance value. In MATLAB, numerical comparison, can clearly reflect the actual assembly of the changes and impact tolerance.
