When performing FRF Based Substructuring (FBS) with experimentally measured Frequency Response Functions (FRFs), measurement noise and variations in the reciprocity of the FRF matrix can create false peaks in the assembled system. This webinar explains how to avoid these false peaks by using modal curvefitting, MLMM method, and enforced reciprocity.
