Research and Application of Measurement Programme of Large Parts of Aircraft Joint System

自从飞机开展数字化设计后,大大提高了飞机装配精度和质量,同时对装配过程的测量也提出了新的要求,因此,只有通过高效的测量手段和方案才能满足飞机装配精度。以大型灭火/水上救援水陆两栖飞机——AG600的三大部件对接为研究对象,基于测量体系的建立和激光跟踪仪测量转站技术,研究飞机大部件调姿的测量技术。该飞机大部件调姿的测量是利用激光跟踪仪对部件上的多个基准点进行测量,通过柔性装配工装实现飞机的姿态调整,进而达到飞机安装要求的测量调姿过程,对于传统测量方法,采用激光跟踪仪进行转站测量的方法,不失为最简单有效的大飞机部件对接测量方法。

Since the development of digital design for aircraft,the accuracy and quality of aircraft assembly have been greatly improved.At the same time,new requirements have been put forward for the measurement of assembly process.Therefore,only through efficient measurement means and schemes can the aircraft assembly accuracy be satisfied.Based on the establishment of measurement system and the transfer station technology of laser tracker,this paper studies the measurement technology of attitude adjustment of large components of the large-scale fire extinguishing/rescue amphibious aircraft AG600.The attitude adjustment measurement of the aircraft’s large parts is based on the measurement of several reference points on the parts by laser tracker,and the adjustment of the aircraft’s attitude is realized by flexible assembly tooling,so as to meet the requirements of the aircraft installation.For the traditional measurement method,the laser tracker is used for the transfer station measurement,which is the simplest and most effective method for the large aircraft parts docking measurement.
