The invention relates to a generator stator core double-frequency vibration parametric calculation method which can be applied to double-frequency vibration analysis of turbonator stator cores. The method is characterized by comprising the steps of parametric modeling of a generator stator core finite element model, parametric loading achieved through formula calculating of stator core electromagnetic exciting force, and automatic output of double-frequency vibration values, vibration deformation mode patterns and vibration response frequency spectrum curve charts of the generator stator cores after calculation. The method overcomes the defects that calculation results are a little bit large in the prior art, double-frequency vibration calculation of various stator cores can be completed, operation is simple, standardization of the calculation method and calculation process is achieved, result errors caused by calculation of different research staff are avoided, the calculation cycle is greatly shortened, and design cost is lowered to a certain extent.
