Abstract
This paper describes the performance of Transient Statistical Energy Analysis (TSEA) for impulsive responses on the beam structures. The properties of response predicted by TSEA are discussed especially in the relation between the response and the loss factors. In order to understand how to measure the subsystem energy transfer which can be compared with the prediction by TSEA, the impulsive responses on two beam structures which are composed of two steel beams with different coupling strengths are measured. As a result, the measurement for responses and excitation should be done at the mean location in a subsystem. Finally, it is shown that the TSEA predictions have good agreement with the measured responses especially in high frequency and in the weak coupling structure.
