| Abstract: | The statistical energy analysis (SEA) method was used to study the active vibration control characteristic of the system. The formulas of the statistical energy of the system and the coupling loss factor (CLF) was derived and the relationship between CLF and the active feedback coefficient was studied. The characteristics of the input power flow, the transfer power flow and the system vibration energy under different damping coefficients were studied in detail. The results are important to engineering problems and the development of SEA method. |
