摘要：

A technique for non-linear system investigation based on the Hilbert transform enables us to identify system instantaneous modal parameters during free vibration analysis and various kinds of excitation of the dynamic system. The direct time domain approach allows the direct extraction of linear and non-linear systems parameters from a measured time signal of input and output. This paper describes forced vibration analysis, and the proposed method determines instantaneous system modal parameters even if an input signal is a high sweep frequency quasi-harmonic signal or random. Some examples of forced vibration analysis of a non-linear system are included. © 1994 Academic Press Limited.
