Identification of weakly nonlinearities in multiple coupled oscillators

Michael Feldman

Research output: Contribution to journalArticlepeer-review


This paper considers the analysis of free nonlinear response of multi-degree-of-freedom (mdof) vibration systems, demonstrating that system skeleton curves are significantly changed in the presence of coupling. The Hilbert transform vibration decomposition together with the modal-spatial coordinate transform allow precise identification of initial nonlinear characteristics.
