Squeeze-film damper design with air channels: Experimental verification
Procedia Engineering, 2011 AbstractThe experimental evaluation of damping-improved parallel-plate geometries is reported in this paper. An improved damper geometry with air channels was developed to address contradictory design constraints: large sensing parallel-plate area is desirable for a significant readout capacitance as well as reduced damping coefficient.
