摘　　要：航空制造业正逐步朝着高精度、高质量的方向发展,数字化测量技术已成为飞机总装的关键。然而,目前的测量场构建主要依赖技术人员的经验,在实施过程中需要反复试错并调整,效率低且人力投入大。为了解决上述问题,提出了一种基于激光跟踪仪的飞机总装数字化测量场构建方法。首先,将飞机总装数字化测量场作为物化模型进行分析研究,提出关键的影响因素。然后,采用模型分析、归纳总结等方法对测量场构建技术进行了研究,通过确定测量场覆盖范围、合理布局增强参考系统(Enhanced Reference System, ERS)点阵、建模仿真、标定ERS点、建立全局坐标系、评价不确定度等步骤,构建了一个科学合理的测量场。该方法在AG600飞机总装中得到了应用验证,证明了其有效性和可行性,可支撑工艺人员高效、准确地构建数字化测量场,满足了飞机总装高精度测量的需求。The aviation manufacturing industry is gradually developing towards high precision and high quality, digital measuring technology become a critical component in the final assembly of aircraft.At present, traditional methods of constructing measuring fields rely heavily on the expertise of technicians, often involving a trial-and-error approach and subsequent adjustments, leading to inefficiency and large manpower input.To solve these problems, a novel method of constructing digital measuring field for aircraft final assembly based on laser tracker is proposed.Firstly, the digital measuring field is analyzed as a physical model to pinpoint key influencing factors.Then, by using model analysis and theoretical summarization, the technologies for constructing the measuring field are studied, and a scientific and resonable measuring field is constructed by determining the measuring field's coverage area, the rational arrangement of the enhanced reference system(ERS) point array, modeling and simulation, calibration of ERS point, establishment of a global coordinate system, and evaluation of uncertainty.The method is implemented and validated in the final assembly of the AG600 aircraft, which proves its effectiveness and feasibility.It enables technical personnel to efficiently and accurately construct digital measuring fields, and meets the high precision measuring demands of aircraft final assembly.
