摘要: 为满足数字化飞机研制环境对结构产品定义的要求,借鉴国外航空企业成功经验,总结了飞机结构产品数字化定义内容的构成.定义了数字化定义中基准类型,并给出应用实例.定义了飞机设计中数字样机的概念,以及其应用范畴.对数字化条件下加工制造进行分析,给出了二维制图的指导原则.提出了融合传统制造信息的概念,总结了工艺信息、质量控制信息在数字化定义中的应用.分析了数字化定义内容信息颗粒度,建立了基于层表的数字化信息管理模式.最终为建立满足航空工业数字化工程中数字化定义技术的应用提供了参考依据.

Abstract: In order to meet the requirement of digital information system deployed in aircraft development, studying the aircraft structure product definition is very important. Based on anglicizing the method and process of aircraft development under the digital circumstance, the content and the form of aircraft structure product definition were summarized. The classes and the transformation principle of the axis and datum system were given for the digital aircraft design. The concept of the digital mockup and its usage were proposed, and the primary principle of the engineering drawings creation was discussed. The manufacture information and the quality control information were integrated into the digital definition to support engineering use. A way to manage all information integrated in the digital definition by layers and filters was introduced. The result consummates the concept of generalized digital definition and provides a reference instruction to implement digital system for aeronautical engineering.
