飞机大部件数字化自动对接装配技术研究

传统飞机大部件对接装配多采用刚性工装对接,该技术精度低、可靠性差、误差补偿难。针对这一问题,介绍飞机大部件数字化对接系统的功能和组成,分析数字化对接系统的四个关键技术。从测量场的构建、对接系统初始位置的标定、对接路径的规划、测量误差的补偿四个方面对某型飞机外翼与中央翼的对接进行研究,实现对接系统的调姿和误差测量与控制,完成外翼与中央翼的精确对接。应用结果表明：采用数字化自动对接装配技术,可有效降低对接误差,提高对接装配的精度和效率。

Research on Digital Automatic assembly Technology of Aircraft Structural Parts
