针对新型飞行器对装配精度需求的不断提高,常用的数字化测量辅助装配系统已无法满足的问题,基于iGPS激光测量系统提出一种新型多装置混合对接测量方法,并基于该测量方法建立位姿测量模型、位姿解算模型和对接路径解算模型。iGPS激光测量系统引导全局对接后,触发局部多数据融合测量系统对局部位姿进行传感,通过局部位姿解算模型即可求解接合耳片之间的角度误差和位置误差,补偿误差后可优化对接路径,从而提高对接精度。实验结果表明,补偿误差后的位置精度达到5.8×10 -2mm,角度精度达到9°×10 -3,说明所提方法满足实际对接精度的需求。

There is growing demand for ensuring accuracy with respect to the assembly of new aircraft. The commonly used digital-measurement auxiliary assembly system cannot meet this demand. In this study, a new multidevice hybrid docking measurement method is proposed based on the iGPS laser measurement system. Further, a position measurement model, position solution model, and docking path solution model are established based on the aforementioned method. After guiding the global docking, the iGPS laser measurement system triggers the local multidata fusion measurement system to detect the local position. The local position solution model can be used to obtain the angle error and position error between the joint ear pieces. The docking path can be optimized after considering the compensation error, improving the docking accuracy. The experimental results indicate that the position accuracy after considering the compensation error is 5.8×10 -2mm and that the angle accuracy is 9°×10 3, indicating that the proposed method meets the actual docking accuracy requirements.
