چکیده
Film damping caused by microfluids has important effects on the dynamic characteristics of moving elements of microelectromechanical system devices. There are two kinds of film damping existing in microelectromechanical system devices, for instance, slide film damping and squeeze film damping. This article presents an overview on the recent research progress on the slide film damping in microelectromechanical system devices. Based on the first slip velocity boundary conditions, this article discusses two kinds of damping models in detail, which commonly used to investigate on the slide film damping. For the convenience of quick reference in future, laterally moving microstructures, adequate important equations and applicable conditions are included in this article. Finally, we proposed two unified models for the analysis and design of laterally moving microstructured devices.

Nonlinear Effects in Squeeze Film Gas Damping on Microbeams
We consider squeeze film gas damping during microbeam motion away and toward a substrate as occurs during opening and closing of RF switches and other MEMS devices. The numerical solution of the gas damping problem in two-dimensional geometries is obtained based on the Boltzmann-ESBGK equation. The difference in damping force between downward and upward moving beams is shown to vary from as lit...
متن کاملA Wavelet Interpolation Galerkin Method for the Simulation of MEMS Devices under the Effect of Squeeze Film Damping
This paper presents a new wavelet interpolation Galerkin method for the numerical simulation of MEMS devices under the effect of squeeze film damping. Both trial and weight functions are a class of interpolating functions generated by autocorrelation of the usual compactly supported Daubechies scaling functions. To the best of our knowledge, this is the first time that wavelets have been used a...

This paper reports analytical modeling and finite element analysis (FEA) of the effect of two types of air damping (squeeze film and slide film damping) on resonance frequency and quality factor of a multi-layer CMOS-MEMS resonator designed for application as a mass sensitive gas sensor. The sensing principle is based on change in frequency or amplitude of the resonator due to adsorption/absorp...

In the current study, the effects of Casimir force and squeeze film damping on pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems are investigated separately. Linear elastic membrane theory is used to model the static and dynamic behavior of the system for strip, annular and disk geometries. Squeeze film damping is modeled using nonli...
متن کاملAn Analytical Model for Squeeze-Film Damping of Perforated Torsional Microplates Resonators
Squeeze-film damping plays a significant role in the performance of micro-resonators because it determines their quality factors. Perforations in microstructures are often used to control the squeeze-film damping in micro-resonators. To model the perforation effects on the squeeze-film damping, many analytical models have been proposed, however, most of the previous models have been concerned w...
