Abstract

An analogy between the instabilities in electrostatic MEMS structures and aeroelastic aircraft wing structures has been inferred in this paper. The static and dynamic analysis of a simple mass-spring model of an electrostatically actuated MEMS structure is presented to understand the pull-in instability. Then the aeroelastic phenomenon occurring on the aircraft wing structures is explained with a simple one degree of freedom wing model. The divergence and flutter instabilities are studied. The control methods taken so far to counteract the instabilities in both cases have been discussed.
