6. Power injected by external forces
In a SEA model, the excitation terms are the powers injected into each subsystem by external forces. It is therefore necessary to estimate these powers from the force fields applied to the various subsystems.
The power injected in the frequency band of width Δω is generally calculated according to the relation :
