A Real-Virtual Mapping Method for Mechanical Product Assembly Process Planning in Virtual Assembly Environment

摘要

In order to realize assembly process planning in virtual reality environment, an assembly process planning generation method based on real-virtual mapping of basic motion sequence is proposed. Based on the analysis of current assembly process content from enterprise, assembly process information is modeled; standard assembly operations and basic assembly motion are defined. The mapping matrix among standard assembly operations and basic assembly motions are set up. A method to get basic motion sequence in virtual environment during virtual assembling process by real user is put forward. A prototype system is developed based on these research results, and the system function is demonstrated through assembly process of automobile engine components. It shows that this assembly process generation method based on real-virtual mapping of motion sequence is feasible, and it also provides a new idea for the application of virtual assembly technique for product manufacturing process.
