Nonlinear damping in nanomechanical beam oscillator
arXiv:cond-mat/0503130
Abstract
We investigate the impact of nonlinear damping on the dynamics of a nanomechanical doubly clamped beam. The beam is driven into nonlinear regime and the response is measured by a displacement detector. For data analysis we introduce a nonlinear damping term to Duffing equation. The experiment shows conclusively that accounting for nonlinear damping effects is needed for correct modeling of the nanomechanical resonators under study.
