Journal Article
Research on high-precision measurement technology for aircraft large-scale tooling assembly
2025
Overview
With the trend of aircraft component assembly moving towards integration, large size, and high precision, more stringent requirements are being placed on assembly fixtures. This paper conducts a technical study on high-precision measurement techniques for large-scale aircraft assembly tooling. It analyzes the measurement error of points based on laser trackers and the error of changing stations in the measurement unit. By locally establishing a networked measurement system composed of laser trackers to form a measurement unit, an optimized multi-lateral measurement algorithm is adopted to calibrate the reference. The calibration accuracy of the reference as a whole is improved through a ring-closed global optimization algorithm, establishing a global measurement coordinate system. The precision of the large-scale measurement field is verified through experiments, and based on this, a method for constructing the measurement field for large-scale assembly fixtures is analyzed and summarized.
