Fully analyzing and solving structural dynamics problems require the power of modal analysis, which separates mode shapes from the overall dynamic response of the structure. The robust modal analysis features of the STAR6 System™ reflect over 15 years of technological leadership.

source link Creating a modal model from FRF measurements involves two steps: identifying the mode locations and accurately estimating the modal parameters of frequency, damping, and residues. The STAR6 System™ provides both capabilities, giving you a variety of options.
get link Simple peak curve fitting methods (coincident, quadrature, and complex peak) provide quick insight into mode shapes. Local single mode (SDOF) and multiple mode (MDOF) polynomial curve fitters are effective for in depth analysis. The global curve fitter is the best solution for modes that are heavily coupled, have high damping, or have many antinodes. The SDOF, MDOF, and global curve fitters consider out of band residual effects to ensure maximum accuracy.
