基于MBD的飞机-装配工装协同变更方法

摘要

装配工装在飞机产品生产过程中处于飞机设计的下游,受到飞机装配件设计及其装配工艺的影响以及飞机生产准备周期限制,时间紧迫,任务繁重.传统的飞机装配工装以文本、二维图形式表达为主,信息是静态的,缺乏唯一的数据源易导致飞机-装配工装协同变更管理效率低、准确性差,针对以上问题提出一种飞机-装配工装协同变更方法:利用基于模型的定义(Model based definition,MBD),建立了飞机和装配工装MBD模型关系架构,并结合相关的变更传播计算方法实现了飞机设计结构变更对装配工装变更影响的主动、自动化预测和分析.通过一套飞机壁板开口加强框的装配工装变更设计实例验证了该方法的可行性.%The design of assembly tooling is located downstream of the aircraft design during the produc-tion of the aircraft ,which is affected by the design of aircraft parts and the limitation of aircraft produc-tion preparation cycle .Its design time is urgent and the task is heavy .Traditional aircraft assembly tooling is mainly expressed in the form of text and two-dimensional drawings ,and the information is static ,w hich results in the lack of unique data sources ,low efficiency and poor accuracy of collaborative change management of aircraft-assembly tooling .In view of the above problems ,a collaborative change method of aircraft-assembly tooling is proposed .Based on the model based definition (MBD) ,the rela-tionship framework of aircraft and assembly tooling MBD models is established .Referring to related change propagation calculation method ,the active and automatic prediction and the analysis of the influ-ence of aircraft design change on assembly tooling change are realized .The feasibility of the method is verified by an example of an assembly tooling change design for an aircraft panel opening frame .
