摘要

飞机装配部件外形尺寸大、曲面形状复杂，型面测量数据量大。现有的单一测量设备测量精度和效率之间的矛盾突出。为此，构建包含激光跟踪仪、关节臂测量仪和摄影测量的数字化组合测量系统。基于坐标变换将多测量站点的测量信息统一到全局坐标系下，通过测量数据模型与理论模型对比，获得部件外形测量结果，在保证测量精度的条件下，提高型面测量效率。以飞机内襟翼上翼面装配过程外形精度保证为例，验证了所提方法的正确性。

Abstract

The aircraft assembly components are typical for large size and complex shape

which makes it need large data for outline inspection. The contradiction between the measuring accuracy and efficiency of the existing single measuring device or measurement field is outstanding. Thus

the digital combined measurement system

including a laser tracker

an articulated arm measuring machine and photogrammetric system

is constructed. Based on the coordinate transformation

the measurement information of multiple stations is unified into the global coordinate system. The measurement results of the component shape are obtained by comparing the measurement data model with the theoretical model

improving the measurement efficiency of the profile surface under the condition of ensuring the measurement accuracy. Taking the assurance of shape accuracy of the flap assembly process for an example

the validity and correctness of the proposed method are verified.
