The concept of surface mobility is introduced to study the identification of distributed loads based on SEA in the paper. The expressions of average surface mobility for the finite plate are derived. By discretizing the acting area, a numerical computation method for average surface mobility is developed. Finally, combining with the complex power method, an identification approach of load power spectrum of distributed loads from the input power of subsystem is set up. The proposed method is validated numerically through an example.
