Abstract

A description and a review of the Hilbert transform procedures for detecting and quantifying structural non-linearity in frequency response functions obtained during modal testing is presented in this paper. A method of minimizing the effect of residual modes of vibration, previously a problem with the numerical Hilbert transform, is also described. © 1987 Pitagora Editrice Bologna.
