Abstract : A direct measurement technique to identify the viscous damping coefficient of one-dimensional devices has been developed. The frequency- dependent properties of the damping coefficient are inherent in this formulation. It has been shown that the variance in the prediction of the damping coefficient is small. The experimental apparatus is extremely easy to build, and the raw data necessary to make the calculations are readily obtained with standard modal techniques.
