The embodiment of the invention discloses a rigidity simulation method for a bearing type covering cap in a full-aircraft model, and the method comprises the steps: calculating the strain corresponding relation between the covering cap and a mouth frame through a static strength test of a wing structure with the bearing type covering cap; obtaining an initial overall strain and the strain corresponding relation according to a finite element analysis model, and determining a rigidity reduction coefficient of the covering cap; multiplying the stiffness reduction coefficient by an actual thickness parameter of the covering cap to obtain a revised thickness of the covering cap; and modifying the thickness of the covering cap in the finite element analysis model according to the revised thickness.
