摘要

对容差分析技术及其理论基础进行了介绍，采用西门子容差分析软件VSA对民用飞机吊挂和机翼对接工艺方案进行研究，对最后装配上连杆或斜撑杆两种方案进行对比分析。研究表明：两种装配方案均需设置工艺补偿，根据影响因素权重报告，需对控制目标影响最大的上下端交点孔设置补偿。因此，根据研究结果，改进了上连杆结构设计方案，上下端交点孔位置在一定范围内可调，从而较好地满足了吊挂与机翼对接的装配协调要求。

Abstract

The paper introduces tolerance analysis technology and its basic theory. The research uses tolerance analysis software VSA to study the process of civil aircraft pylon assembly. The process one: connecting rod is installed at last. The process two: diagonal bracing rod is installed at last. Comparing process one with process two

the following results can be obtained. Both of two assembly programs are required to set the process compensation. According to the weights of influencing factors

some measures should be applied on the greatest effects for control target. Therefore

improve the design of connecting rod structure to make upper and lower nodal hole position in a certain range to meet the coordination requirements of pylon assembly.
