摘要: Abstract In this paper, the influence of centrifugal forces on stability an electro-statically actuated clamped–clamped micro-beam has been investigated. The non-dimensional governing static and dynamic equations have linearized using step by linearization method (SSLM), then, a Galerkin-based reduced order model used to solve equations. For constant value bias DC voltage different values angular velocity equilibrium points corresponding autonomous system including stable center points, unstable saddle singular obtained equivalent mass-spring model. Subsequently bifurcation diagram depicted fixed point. pull-in for calculated. results are validated previous studies good agreement observed. effect force studied phase portraits initial conditions. Moreover, effects behavior investigated time histories velocities.
