| Abstract: | The architecture of a virtual reality based assembly process planning and training system is described. An information decomposition method is put forward to transform data from CAD system to virtual environment. The dynamic constraint recognition and management is studied to implement constraint-based assembly simulation. A process-oriented assembly task model is established to support interactive assembly planning and evaluation. The system is validated by a pump assembly process that it can be used to evaluate and optimise assembly scheme and to guide the workers for training. |
