摘要

飞机柔性装配技术具有鲜明的数字化特点，在并行工程环境下以面向柔性装配的设计思想为指导，对决定飞机质量的关键特性进行定义；通过对制造装配过程中误差累积的分析，将关键特性分解传递到零件和工艺过程；运用数字化技术对各个部段的关键特征进行容差分配，经分配的容差信息将被融入柔性装配数据集作为产品与工装制造、检验的依据。通过对零件和各装配阶段关键特性的检测和监控，可以显著提高飞机装配质量和效率。

Abstract

Flexible assembly is characterized by the digitization

in the phase of the concurrent engineering

according to the idea of design for the flexible assembly

the key characteristics which influences the aircraft quality are defi ned. Through the analysis of the error accumulation

the key characteristics are decomposed to the components and process. Digital technology is used to distribute the tolerance

the tolerance information is added into the dataset of flexible assembly to coordinate the product and tooling’s manufacturing and checkout. By measuring and controlling the key characteristics of the components and process

the quality and effi ciency of the assembly could be conspicuously improved.
