The invention relates to a finite element modeling method for any opening posture of an automobile four-bar linkage hinge front cover. The finite element modeling method comprises the steps that a grid model inp file of the closed state of an automobile front cover system assembly is input; a modal analysis load step is created to verify correctness of a physical state and a connection assembly state of the model; constructing a static analysis load step, and performing displacement to drive a latch hook to perform longitudinal displacement so as to control a target attitude; extracting the target attitude increment step model information of the odb result; automobile front cover target attitude model information is written; the coordinate information in the new attitude model information is replaced with the coordinate information of the original finite element model, and then a finite element model of the target opening attitude of the automobile four-bar linkage hinge front cover is obtained; and extractin
