The invention relates to a parametric modeling method suitable for an end part coil of a generator stator winding. The parametric modeling method is characterized by comprising the steps as follows: step one, inputting geometric parameters of the coil; step two, defining the section shape of the coil; step three, modeling a geometrical model for the end part coil of the stator winding; and step four, establishing a finite element model of the coil. The parametric modeling method suitable for the end part coil of the generator stator winding has the advantages that stator winding end part coil modeling is parameterized, and the finite element model of the end part coil can be established simultaneously, so that the method can be applied to research on vibration characteristics of the stator winding end structure.
