Key Technologies Research In Virtual Assembly System Based On Vega Software

Virtual hand manipulation is a critical technique in virtual assembly and virtual operation. In this paper , we have treated with the following problems: a virtual assembly environment is constructed based on diguy and vega software. A man model is built by adding hand models we create to a man model that diguy software provides. At the same time we define the motion variables of the hand models. And by connecting devices such as 5DT data gloves and FOB tracking system, the man model can be controlled and do many gestures as we move our bodies. And to avoid crossing when two models contact, we improve the collision detection algorithm in vega environment to collide more efficiently and accurately.After researching the robot principle, grabbing forces and grabbing state are analyzed when picking part models. Picking models with mouse in 3D space environment is achieved and path points can be recorded when moving the models. And through these points we can draw an assembly path and replay when we need to check problems in the assembly process.An assembly method based on parts features and assembly force is proposed.
