Studies on visual scene process system of aircraft assembly

According to the aircraft assembly worksite scene process, the hierarchical data model based on PPR (product, process, resources) was got to achieve the conversion in various types of aircraft assembly process data model. At the same time, the lightweight technology and human–computer interactive scene control technology were researched to obtain the lightweight of three-dimensional (3D) model and site scene and the human–computer real-time interaction between people and virtual environment through the computer keyboard and mouse, respectively. And then, the visual assembly sequence planning algorithm based on the parallel binary-coded was suggested to complete the aircraft assembly sequence planning. On the basis of techniques mentioned above, we developed the assembly worksite scene process system, which can be integrated with PDM system. At last, an application case of aircraft nose assembly was given, and the result was proved to be effective.
