基于预装配精度分析的飞机关键装配工序质量控制技术
|
摘要
针对大型飞机机身部件装配过程中经常出现装配精度超差造成的装配返工、返修现象,提出基于预装配精度分析的飞机关键装配工序质量控制技术。首先,对零部件或在制装配件的关键特性点实际坐标信息进行预处理,包括坐标系转换、数据补偿、数据整合与格式转换;其次,基于装配工艺和实测数据,建立基于实测数据的装配工序精度模型,进行预装配精度分析。最后,以某型飞机中机身壁板装配为例,采用激光跟踪仪获得关键控制特性点的三维坐标实测信息,将处理后的实测数据作为装配精度预测模型的输入偏差进行预装配精度分析,实现了中机身壁板的质量控制。
Aiming at the assembly rework and repair problems caused by the poor assembly precision in assembly process of large aircraft fuselage components, the quality control technology for key assembly procedure of aircraft based on preassembly precision analysis is proposed. Firstly, the actual coordinate information of key control characteristic points(KCCPs) of components or in-process assembly parts is preprocessed, including coordinate system transformation, data compensation, data integration and format conversion. Then, according to the assembly process and measured data, an assembly procedure precision model based on measured data is established to perform the pre-assembly precision analysis. Finally, taking the fuselage panel assembly as an example, the laser tracker is used to obtain the measured information of the three-dimensional coordinates of KCCPs, and the processed data are used as the input deviation of the assembly precision prediction model for preassembly precision analysis, so as to realize the quality control of the fuselage panel.
