| Abstract: | In order to obtain the applicable range of statistical energy analysis(SEA) and the key factor in the application of SEA,the model theory is applied to study the input power and the coupling loss factor.The deep-seated meaning of "statistic" in SEA is analyzed in detail.The analysis results show that the large characteristic dimension,high damping broad analytical band,and irrelevant distributing exciting force can all improve the calculation precision of SEA. |
| Keywords: | vibration statistical energy analysis input power coupling loss factor |
