A comparative study of reduced-order modeling techniques for nonlinear MEMS beams
Résumé
This paper is dedicated to the comparison of three techniques of reduced-order modeling(ROM) that may be applied to MEMS beams subject to nonlinear damping and restoring forces.These methods are compared in terms of simplicity and accuracy, in the static, transient andsteady-state regimes. It is shown that one of the most popular ROM methods may lead todramatically wrong results in the case of single-mode decomposition.
