Model-based Definition Assembly Process Information Modeling for Aircrafts

Abstract

Abstract:

To realize the comprehensive application of MBD and get rid of the coexistence of digital quantity and analog quantity in aircraft assembly process planning, a MBD model oriented to assembly process planning was constructed. Through analysis of the aircraft assembly process planning, process informations were divided into four classes: assembly process structure, process features, added process features and supporting information. According to process constitution, the relative mapping operators were customized for all types of information to realize mapping from design model to process model. By multi-view method, all types of process information were represented and managed. And that the process model was divided into three layers: core layer, process extension layer and application layer. Finally, process information MBD model for cabin door was constructed.

Key words: model-based definition(MBD), aircraft assembly, process information, modeling, process planning

摘要：

为了实现基于模型的定义技术在飞机装配工艺设计中的全面应用，摆脱数字量和模拟量共存的数据传递局面，建立了面向装配工艺设计的MBD模型。通过对飞机装配工艺设计过程进行分析，将装配工艺信息分为装配工艺结构、工艺特征、附加工艺特征和工艺配套信息四类。根据信息构成不同，为各类工艺信息定制有针对性的映射算子，建立设计模型向装配工艺模型的映射关系。采用多视图的方法，对装配工艺信息集成模型进行表示和管理，并将其划分为核心层、工艺扩展层和应用层。最后，利用开发的建模工具集建立了某机型舱门的装配工艺信息MBD模型。
