Abstract:At present, the commonly used aircraft assembly quality control methods have poor real-time performance, and can not be corrected until quality problems occur, which can not meet the requirements of high-efficiency and high-quality aircraft assembly. For this problem, the technical characteristics of active real-time control of aircraft assembly quality, such as systematization, are analyzed, and the framework of active quality prevention in assembly design stage and real-time quality feedback control in process stage is established. In the aspect of active prevention, the mechanism and data models suitable for assembly quality prediction are analyzed, and the research status of mechanism prediction modeling and data prediction modeling is explained, moreover, the effects and advantages of combining the two methods are analyzed. In terms of real-time feedback, main directions in quality process control are discussed, such as flexible tooling, drilling and riveting equipment, digital measurement technology at the basic level of control, virtual assembly and quality evaluation at the level of assembly analysis, quality control system and process quality control methods at the level of system management. On this basis, the development directions of aircraft assembly quality control in multi physical quantity assembly, data fusion quality evaluation, quality control system platform application are pointed out.
