| Résumé | The collective nonlinear dynamics of electrostatically coupled nanobeams under parametric excitation is modeled and investigated, while including the main sources of nonlinearities up to the fifth order. The normalized nonlinear differential equations are solved using secular perturbation theory. Numerical simulations have been performed using the Asymptotic Numerical Method for two and three coupled nanobeams. It is shown that, the fifth order nonlinearity leads to an increase in the number of multimodal solutions and their complexity in term of bifurcation topology. This model can be exploited to design arrays of NEMS with high performances for sensing applications. |
