Vibrating Micromirror with Viscous and Thermal Damping: Transient Behavior

Application ID: 49481


Micromirrors are used in certain MEMS devices to control optic elements. This example of a vibrating micromirror surrounded by air uses uses the Thermoviscous Acoustics, Transient, the Shell, and the Pressure Acoustics, Transient interfaces, to model the fluid-solid interaction in the time domain.

The micromirror is initially actuated for a short time and then it exhibits damped vibrations. Using the Thermoviscous Acoustics, Transient interface, the full details of viscous and thermal damping of the mirror from the surrounding air are included.
