3D Design Modification Inspection and Change File Generation of Aviation Hydraulic Shell Parts
In order to improve the efficiency of 3D design change inspection for aviation hydraulic shell parts and resolve the intuitiveness of information expression of traditional change notice,a scheme of automatic 3D design change inspection and visual expression of change information for aviation hydraulic shell parts was designed.The feature recognition technology based on graph matching was studied,the shortest search path and main direction attribute of design features were defined,the change information recognition method based on feature matching was proposed,the change information visualization representation technology based on 3DPDF was studied,and the corresponding system was developed,which not only improved the efficiency of change detection,but also realized the visual representation of change information.
