Approximate periodic solutions to MEMS oscillator subject to
magnetostatic excitation
Abstract
A way to obtain approximate periodic solutions to nonlinear oscillators
arising in a micro-electro-mechanical system (MEMS) is presented for the
case of zero initial conditions and magnetostatic excitation. The
frequency-amplitude relationship is derived by adopting He’s frequency
formulation. The obtained analytical results are illustrated
graphically. The proposed simple approach gives the fast insight into
the dynamics of the singular oscillator and can be useful for design of
MEMS devices.
