飞机部件的外形测量与误差评估是提升飞机装配质量的关键。针对测量工作要求高精度、高效率和无需专用工装的情况,同时针对被测对象外形尺寸大、各部位测量规范不同等难点,提出一种基于激光跟踪仪的智能移动三坐标辅助定位自适应控制技术。该技术以激光跟踪仪作为测量工具,以直角三坐标伺服机构作为靶标的辅助定位装置,通过对直角三坐标伺服机构及导航小车进行任务规划与优化;同时激光跟踪仪实时反馈靶标目标位置,从而以最优路径的方式实现对测量机构多站位自主移动的全闭环自适应控制,提高了靶标的定位精度及测量效率。本文在线对测量数据进行了快速处理,得出了误差分布图,并精确地反映了测量点位的误差。实验结果表明：该方法可实现大尺寸部件的高精度快速测量,满足飞机大部件的测量要求。

英文摘要：

The shape measurement and the error evaluation of aircraft components are keys to the improvement of aircraft assembly quality.Since the target object is usually very large and different components have different test standards,to fulfill the demands of high precision,high efficiency and no special tooling for the measure system,an adaptive control method of intelligent three-dimensional（3D）mobile platform based on laser tracker is proposed.This technology uses the laser tracker as measurement tool and regards rectangular 3Dservo mechanism as the auxiliary positioning device for the target.By receiving the target position from the tracer dynamically,an entire closed-loop control of multi-station and autonomous mobile of the measurement mechanism with the optimal path is realized based on the task planning and the optimization of the 3Dservo mechanism and the guided vehicle,thus improving the positioning accuracy of the target and the efficiency of measurement at the same time.The measured data are analyzed online rapidly,and the error distribution is obtained,which accurately reflects the measure error.Experimental results show that the method has high precision and can be used to measure large components effectively,which meets the requirements of aircraft component measurement.
