Modal Dominancy Analysis Based on Modal Contribution to Frequency Response Function ?2 ? 2 -Norm
The main restriction in modal reduction techniques is in the lack of proper dominancy procedure. A modal dominancy procedure for modal dominancy analysis of mechanical systems is presented. Also a SVD-based technique to improve the reduction effectiveness in moving and distributed loading problems is presented.
