Identification of a nonlinear beam through a stochastic model based on a Duffing oscillator

Résumé

A nonlinear beam-shaker system was approximated by a Duffing oscillator; The modal parameters were estimated by stochastic methods; Nonlinear coefficient was estimated through the restoring force surface method; The stochastic model was validated with new experimental data and Monte-Carlo simulations.
