Abstract : The basic principle of statistical energy analysis (SEA) was demonstrated, some domestic car was divided to 41 subsystems using SEA, and the car 3D model was established. Input parameters of regular-shape subsystems were computed using analytical method, modal density of the complex structure subsystem was tested by admittance method, and damped loss factor of the complex structure subsystem was also tested by steady energy stream method. The coupling loss factor of structure-structure, structure-cavity, and cavity-cavity was computed. Engine excitation and road excitation were measured by roa
