计算机辅助飞机制造协调路线图设计研究

摘要

In order to solve the problem that there is no digital document between coordination route planning and tolerance design, this paper studies the computer aided design of aircraft manufacturing coordination route diagram to realize digitalized expression of this route and based on the analysis of process, defines the icons of this diagram. then divides the its design flow into four parts:co-ordination type selection, icons adding, coordination relations adding and automatic layout of icons. Then based on these, the draw-ing scheme is described in detail by UML and the information of route diagram is stored efficiently by tree structure. Final y, the coor-dination route diagram for aircraft manufacturing is built automatical y based on layout algorithm. The above system is developed and the perfect result is achieved in the practice.%为了实现飞机制造协调路线的数字化表达，建立飞机制造协调路线规划和容差设计之间的数字化桥梁，对计算机辅助飞机制造协调路线图设计进行研究。通过对飞机制造协调过程进行分析，定义了协调路线图图符，并将计算机辅助飞机制造协调路线图设计流程简化为4个部分：确定协调类型、添加协调图符、确定协调关系、图符自动布局。以此为基础，建立基于UML的协调路线图设计方案，采用树结构对协调路线图进行存储，并提出了图符自动布局算法。据此开发了计算机辅助飞机制造协调路线图设计系统，在实用中取得了良好的效果。
