N2 - In this paper, methods of acquiring internal loss factors and coupling loss factors by experimental measurement are investigated. The internal loss factor and coupling loss factor of two coupled plates is measured by the modified power injection method. The SEA model of coupled system is established based on the measured results of internal loss factor (ILF) and coupling loss factor (CLF). A random vibration analysis is conducted as a validation example. Since the formulation solution and measured result agree preferably, the validity of the measurement method and the effectiveness of analyzing vibration response using SEA are proved.
