8. Appendix 3: Appropriation methods

8.1 Appropriate force structure

The equation expressing the forced response to a harmonic excitation of pulsation ω is written :

(K - ω ² M + jωB)y = f ^( 26 )

From the equilibrium equation (26) , we can give the form of the appropriate force f _ν to generate the normalized response y _ν (respectively $f_{ν}^{'}$ ...
