Abstract：Aiming at the requirements of localization and posture alignment in aircraft digital assembly, the 3-UPS
parallel mechanism which has 6-DOF was introduced as an aircraft assembly posture and positioning system. First, to
improve the aircraft components assembly precision, an effective length model of 3-UPS was establish by analysis the
kinematic pair error clearance between hinge. Then, the positioning accuracy model of this system was obtained based on
parallel mechanism positive position solution. Finally, the influence of the positioning mechanism motion precision by the
kinematic pair error clearance between hinges was simulated in MATLAB, and the results of the analysis provide a theoretical
basis for control compensation.
