The fundamental characteristic of aircraft assembly is assembly measurement
accuracy. A single digital measurement device can meet the requirements of an
analytical and small surface. But a single digital measurement device cannot
meet the measurement requirements for synthetic and large surfaces, such as
fuselage panel components. This research aims to establish a combined
measurement method to improve the measurement quality and extend the measurement
area. The method demonstrated the combined measurement method utilizing a
combination of the laser tracker and the articulated arm measuring machine. In
this research, the combined measurement system is constructed based on the
complexity and large size of the fuselage panel. The articulated arm measuring
machine is used to scan the surface of the panel components accurately and the
coordinate conversion of the common points measured by the laser tracker to
realize the shape of the aircraft fuselage panel. Then the measurement process
of the combined measurement technique drew up, and the measurement data
processing method is analyzed. Finally, the deviation vector matrix and the
chromatogram deviation distribution are obtained to realize the measurement
accuracy of the new combined measurement device. It is evident that the
measurement accuracy for the fuselage panel assembly process is improved by
utilizing combined measurement technology. Also, the current research reduces
the assembly time and increases the assembly efficiency compared with the
traditional measurement system. Through experimental analysis, the innovation is
efficient and feasible. Also, it has a certain application value in the modern
aerospace industry.
