Numerical study of mathematical models of micromechanics with periodic impulse action

We consider the results of the numerical study of mathematical models of two microelectromechanical systems (MEMS). We formulate matematical models as initial boundary value problems describing the cylindrical flexure of the elastic beam as a movable electrode under the action of a repetitive intensity impulse of the electrostatic field between the movable and fixed electrodes in a microgap. In the first problem, both ends of the beam are rigidly fixed, and in the second problem, we consider a cantilever beam. The range of the parameters is found for a model having two periodic solutions with periods of impulse interaction one of which is stable and the other is unstable.
