An alternative reduced order model for electrically actuatedmicro-beams under mechanical shock
This study focuses on the effect of mechanical shock on dynamic pull-in instability of eclectically actuatedmicro-beams through an alternative reduced order model (ROM). The model’s predictions for dynamicpull-in voltages are compared with available...
On the Response of Clamped-Clamped Nano-Electro-Mechanical Beam under Mechanical Shock Incorporating the Casimir Force
reduced order modelling is utilized to solve the problem. It is found that considering the Casimir force and shock pulse interaction may lead to early instability in nano-electro-mechanical devices through dynamic pull-in even in the case with no applied...

to be induced according to the base excitation scheme. The micro-plate motion is simulated through a novel and computationally very efficient reduced order model which accounts for the inherent non-linearity of distributed electrostatic pressure...
Dynamic Pull-in Investigation of a Clamped-Clamped Nano-Electro-Mechanical Beam under Ramp-Input Voltage and the Casimir Force
-N/MEMS. The presented model is nonlinear due to the inherent nonlinearity of electrostatics and the Casimir excitations as well as the geometric nonlinearity of midplane stretching. A Galerkin based reduced order modeling is utilized. It is found that the calculated...
Investigation of Dynamic Pull-in Instability in Clamped-Clamped Nanobeam-Based NEMS Devices under Intermolecular Surface Forces
is nonlinear due to inherent nonlinearity of Casimir and van der Waals forces and geometrical nonlinearity such as midplane stretching of this elastic beam. First the Reduced Order Model (ROM) for a clamped-clamped nanobeam-based N/MEMS switches under Casimir...
Modeling and Dynamic Performance Analysis of Brushless Doubly Fed Induction Machine Considering Iron Loss
Brushless doubly fed induction machine (BDFIM) which is able to operate in both induction mode and synchronous mode, has received increasing attention of researchers, in the last three decades. It could be considered as ...
