An analysis method of relative position accuracy in aircraft assembly was proposed under the condition of digital measuring. First

an agile analysis framework of relative position accuracy was constructed

within which the evaluation of relative position accuracy was transformed into the estimation of relative position between measuring points on airplane. Then

a configurable software tool on the basis of the constructed model was developed to analyze and visualize the relative position accuracy of airplane rapidly and vividly. Subsequently

a case study of the relative position accuracy analysis of an airplane landing gear was provided to verify the feasibility and validity of the method.
