Research output: Patent

Abstract

The first aspect of the invention is related to a new method for automatically detecting physical modes within the data resulting from a modal analysis estimation algorithm (e.g. LSCE, PolyMax or other). The automatic detection method of the invention is based on a non-hierarchical clustering method wherein the number of clusters is automatically optimized, further making use of a metric for spuriousness within each cluster. According to the second aspect of the invention, the method for automatically detecting modes is used in a method removing harmonics from a signal.
