Year: 2025
Type: conference-paper
Abstract: 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.
