飞机装配协同测量技术应用

Application on Cooperative Measure Technology for Aircraft Assembly

针对飞机装配对大尺度、高精度、多任务和快速测量的需求,介绍了面向飞机数字化装配的测量基准标定、测量设备协同工作模式等方法,阐述了多系统协同测量的技术方案,基于USMN(Unified Spatial Metrology Network)构建包络飞机全尺寸的测量基准网,形成适应飞机装配的多系统协同测量模式,可实现内部隐藏特征、孔位信息、轴线、配合型面、气动外形和间隙阶差的测量,满足了飞机装配的三维数字化测量需求。最后以全机对合测量与大型零部件表面测量为例,验证协同测量的有效性。

To meet requirements of measure during aircraft assembly process,such as big dimension,high accuracy,multitask and quick measure,the methods are developed including precision calibration of measure basis network facing on aircraft digital assembly,multi-systems cooperative measure,and technology solutions are described.Then measuring basis network covering total aircraft based on USMN is built to improve accuracy measuring reference.Work pattern of cooperative measure including multi-system is established to extend measuring scope and accuracy.The method was developed in this paper can realize the measurement of internal hidden features,hole position information,axis,mating surface,aerodynamic profile,flush and gap on the aircraft skins,meets the requirements of three-dimensional digital measurement for aircraft assembly.At last,the methods of cooperative measure are validated by measure process experiment of huge components assembly and huge parts surface feature including aerodynamic profile,flush and gap on the aircraft skins.
