The invention relates to the field of flexible thin plate workpiece positioning deviation analysis, and discloses an N-2-1 positioning based aircraft skin positioning deviation analysis method. The method comprises the steps of firstly, determining an initial positioning state and a rigid positioning deviation of skin through deterministic positioning deviation analysis; and secondly, based on Matlab programming and finite element analysis software, realizing over-positioning deviation analysis of the skin through contact force change and deformation analysis in a skin multi-stage clamping process. According to the method, the initial positioning state of skin positioning and the influence of the contact force change in the skin clamping process on the skin deformation are fully considered, so that the influence of a skin practical positioning and clamping process on a final positioning deviation can be reflected more accurately.
