Structural intensity presents the energy transmission on structures. Statistical Energy Analysis which is based on the idea of energy transmission is an effective tool to analyze the structural vibration in middle and high frequency range. This paper discusses the structural vibration analysis using structural intensity measurement. The 5 points method using five sensors gives us the energy transmission path, and the wave decomposition method provides us with the position of excitation source and the mean intensity. In this paper, these methods are applied to some plate-like structures and a front door panel of a vehicle. As a result, it is shown that these methods are applicable and the results are effective to analyze the structural vibration.
