Investigation of length and initial gap variation on pull-in voltage of multilayered micro-beam
In this work, a multilayered fully clamped micro-beam is modeled using commercial FEM software (COMSOL
Multiphysics). The model is designed to investigate the pull-in instability of the multilayered micro-beam under
the effect...
Material and Geometrical Characteristics Investigation of Micro-beam on Pull-in Voltage Using FEM and Taguchi DOE
In this work, a fully clamped micro-beam is modeled using commercial FEM software (COMSOL
Multiphysics). The model is designed to investigate the pull-in instability of the micro-beam under the effect of
electrostatic field induced...
Pull-In Instability of Electrically Actuated FGM Micro-Beam Under the Mechanical Shock Based on Modified Couple Stress Theory
This investigation concentrates on the combined effect of mechanical shock and electrostatic
loads on the dynamic pull-in instability of functionally graded micro-beams. An alternative
reduced order model (ROM) is employed to study...
A Frequency Criterion for Doubly Clamped Beam-Type N/MEMS subjected to the van der Waals Attraction
In general, the vibration frequency of electrically actuated nano/micro-beams under suddenly applied DC voltage is decreased with an increase of the input voltage. However, this descending behavior may be changed, if the initial gap between...
INFLUENCE OF FRINGING FIELD EFFECT ON THE PULL-IN OF SIZE DEPENDENT MICRO-BEAMS
This study investigates influence of fringing field effect
on the voltage dependent behavior of electrostatically
actuated micro-beams. For this purpose, the size
dependent beam model is used. Strain gradient...
Transient Characteristics of Microelectromechanical Systems Considering Squeeze Film Damping and Electrostatic Actuation
parametric study. In addition, the accuracy of present method is verified by comprising the results with experimental data and excellent agreement between them are observed. It is found that by decreasing the resistance of fluid pressure, micro-beam...
