The invention discloses a rapid equivalent modeling method for a composite material thin-wall bolt connection composite structure, relates to the technical field of rapid equivalent modeling of composite material thin-wall bolt connection composite structures, and aims to solve the problem that the composite material thin-wall bolt connection composite structure is low in calculation efficiency onthe premise that the calculation precision is ensured. The method comprises the steps that geometric information of bolts is picked up, clamping faces corresponding to the bolts, the total number ofthe clamping faces and influence areas corresponding to the clamping faces are determined according to the geometric information of the bolts, and the bolts are deleted; parts which can be ignored byequivalent modeling are deleted; The thin-wall part is shell-shaped, and corresponding thickness information is recorded; Hole edge circular lines of the bolt holes in the shell are deleted; an equivalent connection unit is established and the composite material of the equivalent connection unit is endowed with equivalent connection rigidity; the shell is endowed with attributes; grid division isperformed on the shell; And binding setting and contact setting are carried out between the adjacent shells according to the influence areas, and modeling is completed. The method is suitable for modeling the thin-wall bolt connection combination knot.
