Research on Virtual Assembly Technology Based on 3D Modeling Method

Abstract

Aiming at the current situation that there is lacking in-depth study on applications of virtual technology in mechanical manufacturing and assembly process control, the virtual assembly systems was researched and designed based on combining virtual reality technology with mechanical assembly process. The support mechanism of virtual assembly platform was designed based on taking shaft parts as example, and modeling method of 3D features parameters was adopted in order to build the model of virtual assembly parts, which was modeled according with the sequence as describing physical feature parameters of parts, building data structure of feature parameters and building model features library. On the basis of modeling virtual assembly platform, the key technologies of realizing the virtual assembly processing, which was from positioning issue and collision detection issue, were also analyzed, and control methods of virtual assembly processing were pointed out in detail. All is work is significative for enhancing the level of virtual technology applications, digital machinery manufacturing and assembly.
