Analysis of isolated solutions in a symmetric MEMS array during symmetry breaking event using NNM

Abstract : These works analyze isolated solutions in a symmetric 2-beam MEMS array designed for mass detection using Nonlinear Normal Modes (NNM) during symmetry breaking event. While symmetric, the system present two pure NNM and one mixed NNM. Then an added mass is dropped onto the MEMS array, the symmetry is broken and an isolated NNM is appearing. Particular behaviors on the isolated solutions depend on which type of NNM the isolated solution are linked to. The originality lies in the detection and analysis of isolated solution and NNM before and after symmetry breaking in a MEMS array using bifurcation calculation and continuation methods.
