Identification of Nonlinear Multi-Degree-of-Freedom Systems : Presentation of an Identification Technique
TL;DR: In this paper, a new technique of identifying nonlinear multi-degree-of-freedom systems has been presented, where the basic procedures of this technique are : (1) obtaining the data of a periodic external force applied to the system and of the periodic steady-state response induced by it; (2) expressing the nonlinear terms of the system in the form of polynomials with unknown coefficients; and (3) determining the unknown coefficients by expressing the necessary quantities in Fourier series and applying the principle of harmonic balance.
