摘要

Statistical Energy Analysis (SEA) method is utilized to investigate the vibration energy of structure-borne found. This method analyses the complex connected structures with many vibration modes received stationary random vibration in broad-band excitation, if the natural frequencies within the frequency bandwidth are statistically distributed. The present paper describes equations of power balances and coupling loss factors between coupled systems from theoretical perspective.
