The invention relates to the technical field of composite materials, in particular to a composite material grid structure rib section shape analysis method based on soft film forming. The method comprises the steps of calculating an initial section shape of a composite material grid structure rib under the action of normal stress based on a pre-constructed soft film-composite material finite element model; the normal stress is a vertical extrusion force between the soft film and the composite material grid structure when the soft film is utilized to generate the composite material grid structure; a shear layer between the soft film and the composite material grid structure is determined in advance when the soft film is used for generating the composite material grid structure; applying a shear layer to the initial section of the composite grid structure rib to obtain an extrusion-shear effect coupling analysis model; and solving the extrusion-shearing effect coupling analysis model to obtain the final section
