摘要

摘要: 针对因厂房地基下沉等因素引起的飞机数字化装配体系中公共基准点产生偏差的问题,提出一种飞机装配坐标系公共基准点粗差检测与校正方法.该方法通过泰勒展开布尔沙-沃尔夫空间坐标转换模型形成了适用于大旋转角的坐标系转换线性模型,并结合拟准检定法检测并估算偏差较大的基准点,进而给出了公共基准点在装配全局坐标系下的坐标修正模型.采用激光跟踪仪对公共基准点进行测量并用上述方法修正公共基准点坐标.实验证明,该方法能有效检测粗差并修正,提高飞机装配坐标系的精度.

Abstract: A gross error detection and correction method of the public reference point in an aircraft assembly coordinate system was proposed for such deviations of a public reference point in a digitalized aircraft assembly system as resulted from foundation sinking of a workshop or other factors. In this method, a coordinates transformation linear model applicable to a large rotation angle was built by expanding the Bursa-Wolf coordinates transformation model in Taylor' s expansion, and in combination with the method of quasi-accurate detection (QUAD), the reference point with a relatively large deviation was detected and estimated, and further a coordinates correction model of the public reference point was put forward in a global coordinates for assembly. The public reference point was measured with a laser tracker and then the public reference point coordinates was corrected by the abovementioned method. Experiments prove that the gross error could be effectively detected and corrected by this method, thus the precision of the aircraft assembly coordinate system could be improved.
