摘要
为了提升航空液压壳体零件三维设计变更检查的效率,并解决传统更改通知单信息表达不够直观的问题,设计了航空液压壳体零件三维设计变更检查自动化及更改信息可视化表达方案.研究基于图匹配的特征识别技术,定义设计特征最短搜索路径和主方向属性,提出基于特征匹配的更改信息识别办法,研究基于 3DPDF的更改信息可视化表达技术,开发相应的系统,在提高更改检查效率的同时实现了更改信息的可视化表达.
Abstract
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.
