Exploitation of a method based on coupling techniques in which a single concentrated Force is applied without generation of a Moment excitation.

The objective is to determine Rotational FRFs without application of a Moment. The method is based on FRF coupling and on structural modification, where the influence on the use of different fixtures and the generation of spurious peaks are discussed.
