Abstract: To realize numeralization, automation and flexibility during large aircraft components assembly, a novel posture alignment and joining test system for large aircraft fuselages is developed. Firstly, the working principle of the test system is introduced. Based on test-fuselages’ measurement data from the laser tracker, test-fuselages’ postures are calculated by integrated management system, and several three coordinate numerical control localizers are driven to move harmoniously by control system, to achieve test-fuselages’ posture alignment and joining. Secondly, the kinematics model for the posture alignment system is established. The relevant software, including integrated management system, measure system and control system, are developed and integrated on the basis of the hardware platform. Finally, the test system is applied to simulate test-fuselages’ posture alignment and joining. Experimental results show that test-fuselages’ position alignment precision is better than 0.09 mm, and test-fuselages’ posture alignment precision is better than 0.000 5°. Some technologies of the test system have been successfully applied in several national key projects, which can greatly improve the quality and efficiency of the aircraft assembly.
