虚拟飞机姿态评价系统在数字化装配中的应用

Application of Virtual Aircraft Position Estimation System in Digital Assembly

目前飞机大部件数字化调姿、定位技术在飞机制造业得到了推广及应用,但在飞机大部件调姿、定位过程中,不同测量点的选择可能造成不同的飞机姿态;零件制造、部件装配、测量设备等各环节引入的误差积累也会导致飞机位姿状态与飞机理论模型的偏差,飞机状态无法与理论位置最佳匹配。为最小化飞机姿态误差,提高飞机调姿、定位效率,提出一种用于飞机大部件数字化装配系统的飞机虚拟调姿姿态评价子系统,通过对系统在现场应用所得到的测量数据进行分析,本系统能实际应用于飞机大部件数字化调姿、定位。

Digital posture adjustment and assembly positioning technology of large parts of the aircraft is widely used, some application systems is used in the assembly worksites. However, during the course of the aircraft assembly positioning, the different choice of the measuring points will cause different aircraft state. Parts machining, assembly, measuring equipment, etc. will also bring error, that makes deviation between the state of the practical position and the theoretical state of the aircraft, and the aircraft can not be positioned right for the next operation. To minimize the error of the aircraft positioning and improve the efficiency, a kind of virtual aircraft position estimation system using on digital assembly is applied, from the analysis of the measuring data during the aircraft poisoning, this virtual aircraft position estimation system can be practically used during the positioning of the aircraft.
